PostgreSQL: Downloads – Postgresql 9.3 download for windows 10 free
This release contains a variety of fixes from 9. For information about new features in the 9. Also, if you are upgrading from a version earlier than 9. When processing a crafted timestamp formatting template, PostgreSQL would write past the end of a buffer. Either case could crash the server. We have not ruled out the possibility of attacks that lead to privilege escalation, though they seem unlikely.
PostgreSQL includes a replacement implementation of printf and related functions. This code will overrun a нажмите сюда buffer when formatting a floating point number conversion specifiers eEfFg or G with requested precision greater than about This will crash the server, and we have not ruled out the possibility of attacks that lead to privilege escalation. While that is the only affected core PostgreSQL functionality, extension modules that use printf-family functions may be at risk as well.
PostgreSQL uses the system implementation of these functions where adequate, which it is on other modern platforms. Errors in memory size tracking within the pgcrypto module permitted stack buffer overruns and improper dependence on the contents of uninitialized memory. The buffer overrun cases can crash the server, and we have not ruled out the possibility of attacks that lead to privilege escalation.
If any error occurred while the server was in the middle of reading a protocol message from the client, it could lose synchronization and postgresql 9.3 download for windows 10 free try to interpret part of the message’s data as a postgresql 9.3 download for windows 10 free protocol message. An postgresql 9.3 download for windows 10 free able to submit crafted binary data within a command parameter might succeed in injecting his own SQL commands this way. Statement timeout and query cancellation are the most likely sources of errors triggering this scenario.
Particularly vulnerable are applications that use a timeout and also submit arbitrary user-crafted data as binary query parameters. Disabling statement timeout will нажмите чтобы прочитать больше, but not eliminate, the risk of exploit. Our thanks to Emil Lenngren for reporting this issue. Some server error messages show the values of columns that violate a constraint, such as a unique constraint.
If the user does not have SELECT privilege on all columns of the table, this could mean exposing values that the user should not be able to see. Adjust the code so that values are displayed only when they came from the SQL command or could be selected by the user. This closes on Windows the same vulnerability previously closed on other platforms, namely that other users might be able to connect to the test postmaster.
Non-ASCII locale names are problematic since it’s not clear what encoding they should be represented in. Fix incorrect processing of CreateEventTrigStmt. This case is only known to arise when an extension creates both a datatype and a table using that datatype. This requirement was missed if the index belonged to an inheritance child table, so that it was possible to incorrectly return rows that no longer satisfy the query condition.
This restriction is per SQL standard. Previously we did not reject the case explicitly, but later on the code would fail with bizarre-looking errors. A negative offset value has been an error since 8. Restore the expected behavior. This change causes domains over numeric postgresql 9.3 download for windows 10 free boolean to be treated like their base types for purposes of conversion to JSON.
It worked like that before 9. The previous code could get a wrong answer, or consume excessive amounts of time детальнее на этой странице memory before realizing that the answer must overflow. A numeric value’s display scale dscale should never be less than the number of nonzero fractional digits; but apparently there’s сильно cisco anyconnect 3.1 download windows 10 free весьма least one broken client application that transmits binary numeric values in which that’s true.
This leads to strange behavior since the extra digits are taken into account by arithmetic operations even though they aren’t printed. The least risky fix seems to be to truncate away such “hidden” digits on receipt, so that the value is indeed what it prints as. Matching would often fail ссылка на подробности the number of allowed iterations is limited by a? There’s no use-case for such large UTC offsets, so reject them. Two different terms would be considered to match if they had the same CRC.
Also, if the second operand had more terms than the first, it would be assumed not to be contained in the first; which is wrong since it might contain duplicate terms.
The previous coding could crash on an oversize dictionary, so this was deemed a back-patchable bug fix rather than a feature addition. Previously, the xml value resulting from an xpath call would not have namespace declarations if the namespace declarations were attached to an ancestor element in the forest games download for pc free xml value, rather than to the specific element being returned.
Propagate the ancestral declaration so that the result is correct when considered in isolation. Ensure that whole-row variables expose nonempty column names to functions that pay attention to column names within postgresql 9.3 download for windows 10 free arguments Tom Lane. This is fixed properly as of 9.
In some cases this will be the underlying table’s column name rather than the query-assigned alias that should theoretically be visible. This patch fixes corner-case “unexpected operator NNNN” planner errors, and improves the selectivity estimates for some other cases.
Fail cleanly when a GiST index tuple doesn’t fit on a page, rather than going into infinite recursion Andrew Gierth. The previous behavior resulted in basically ignoring these per-table settings, which was unintended. Now, a table having such settings will be vacuumed using those settings, independently of what is going on in other autovacuum workers.
Even when autovacuum postgresql 9.3 download for windows 10 free nominally off, we will still launch autovacuum worker processes to vacuum tables that are at risk of XID wraparound.
However, such a worker process then proceeded to vacuum all tables in the target взято отсюда, if they met the usual thresholds for autovacuuming.
This is at best pretty unexpected; at worst it delays response to the wraparound threat. Fix it so that if autovacuum is turned off, workers only do anti-wraparound vacuums and not any postgresql 9.3 download for windows 10 free work. During crash recovery, ensure that unlogged relations are rewritten as empty and are synced to disk before recovery is considered complete Abhijit Menon-Sen, Andres Freund.
This prevents scenarios in which unlogged relations might contain garbage data following database crash recovery. Fix race condition between hot standby queries and replaying a full-page image Heikki Linnakangas. Prevent latest WAL file from being archived a second time at completion postgresql 9.3 download for windows 10 free crash recovery Fujii Masao.
Avoid creating unnecessary. Change “pgstat wait timeout” warning message to be LOG level, and postgresql 9.3 download for windows 10 free it to be more understandable Tom Lane. This message was originally thought to be essentially a can’t-happen case, but it occurs often enough on our slower buildfarm members to be a nuisance. Postgresql 9.3 download for windows 10 free it to LOG level, and expend a bit more effort on the wording: it now reads приведу ссылку stale statistics instead of current ones because stats collector is not responding”.
Warn if macOS’s setlocale starts an unwanted extra thread inside the postmaster Noah Misch. Unexpected behavior ensued if the first occurrence of dbname contained a connection string or URI to be expanded. Depending on kernel behavior, libpq might return an empty error string rather than something download player for free when the server unexpectedly closed the socket. If PQreset is called repeatedly, and the connection cannot be re-established, error messages from the failed connection attempts kept accumulating in the PGconn ‘s error string.
Properly handle out-of-memory conditions while parsing connection options in libpq Alex Shulgin, Heikki Linnakangas. In initdbgive a clearer error message if a password file is specified but is empty Mats Erik Andersson. Fix that by printing the history ourselves rather than having the library do it. A pleasant side-effect is that the pager is used if postgresql 9.3 download for windows 10 free. This patch also fixes a bug that caused newline encoding to be applied inconsistently when saving the command history with libedit.
Multiline history entries /28582.txt by older psql versions will be read cleanly with this patch, but perhaps not vice versa, depending on the exact libedit postgresql 9.3 download for windows 10 free involved.
Improve consistency of parsing of psql ‘s special variables Tom Lane. Recognize all values for all these variables case-insensitively; previously there was a mishmash of case-sensitive and case-insensitive behaviors.
With an operating system crash and some bad luck, this could result in data loss during an upgrade. This could result in failure because not all 9. X versions have that parameter. Fortunately, we don’t actually need to set it at all.
This oversight did not bother PostgreSQL proper, but could confuse some external replication tools. It now prints that row but doesn’t recurse further. The previous over-conservative marking was immaterial in normal use, but could cause optimization problems or rejection of valid index expression definitions. Since the consequences are not large, we’ve just adjusted the function definitions in the extension modules’ scripts, without changing version numbers.
These changes are mostly cosmetic but in some cases fix corner-case bugs, for example a crash rather than a proper error report after an out-of-memory failure. None are believed to represent security issues. This results in a very substantial reduction in disk space usage during make check-worldsince that sequence involves creation of numerous temporary installations.
However this assumption fails in the real world, so introduce the ability for a zone abbreviation to represent postgresql 9.3 download for windows 10 free UTC offset that sometimes changes. Update the zone abbreviation definition files to make use of this feature in timezone locales that have changed the UTC offset of their abbreviations since according to the IANA timezone database.
Remove references to ADT as “Arabia Daylight Time”an abbreviation that’s been out of use since ; therefore, claiming there is a conflict with “Atlantic Daylight Time” doesn’t seem especially helpful. Accordingly, adopt these names into our “Default” timezone abbreviation set. Also, numerous corrections for historical pre time zone data. Unsupported versions: 9.
