Er zijn updates verschenen voor alle nog ondersteunde versies van PostgreSQL. Dit populaire 'opensource relational database management system' draait op een groot aantal besturingssystemen en is daardoor uitstekend inzetbaar in diverse omgevingen. Het is een afgeleide van Ingres, nadat de hoofdontwikkelaar daarvan voor zichzelf is begonnen en deze database van opensource closedsource werd. De release notes voor deze uitgave kunnen hieronder worden gevonden.
PostgreSQL 13.2, 12.6, 11.11, 10.16, 9.6.21, and 9.5.25 Released!The PostgreSQL Global Development Group has released an update to all supported versions of our database system, including 13.2, 12.6, 11.11, 10.16, 9.6.21, and 9.5.25. This release closes two security vulnerabilities and fixes over 80 bugs reported over the last three months. Additionally, this is the final release of PostgreSQL 9.5.

Security IssuesBug Fixes and Improvements
- CVE-2021-3393: Partition constraint violation errors leak values of denied columns
Versions Affected: 11 - 13.
A user having anUPDATE
privilege on a partitioned table but lacking theSELECT
privilege on some column may be able to acquire denied-column values from an error message. This is similar to CVE-2014-8161, but the conditions to exploit are more rare.
The PostgreSQL project thanks Heikki Linnakangas for reporting this problem.- CVE-2021-20229: Single-column SELECT privilege enables reading all columns
Versions Affected: 13.
A user having aSELECT
privilege on an individual column can craft a special query that returns all columns of the table.
Additionally, a stored view that uses column-level privileges will have incomplete column-usage bitmaps. In installations that depend on column-level permissions for security, it is recommended to executeCREATE OR REPLACE
on all user-defined views to force them to be re-parsed.
The PostgreSQL project thanks Sven Klemm for reporting this problem.This update fixes over 80 bugs that were reported in the last several months. Some of these issues only affect version 13, but could also apply to other supported versions.
Some of these fixes include:
- Fix an issue with GiST indexes where concurrent insertions could lead to a corrupt index with entries placed in the wrong pages. You should
REINDEX
any affected GiST indexes.- Fix
CREATE INDEX CONCURRENTLY
to ensure rows from concurrent prepared transactions are included in the index. Installations that have enabled prepared transactions shouldREINDEX
any concurrently-built indexes.- Fix for possible incorrect query results when a hash aggregation is spilled to disk.
- Fix edge case in incremental sort that could lead to sorting results incorrectly or a "retrieved too many tuples in a bounded sort" error.
- Avoid crash when a
CALL
orDO
statement that performs a transaction rollback is executed via extended query protocol, such as from prepared statements.- Fix a failure when a PL/pgSQL procedure used
CALL
on another procedure that hasOUT
parameters that executed aCOMMIT
orROLLBACK
.- Remove errors from
BEFORE UPDATE
triggers on partitioned tables for restrictions that no longer apply.- Several fixes for queries with joins that could lead to error messages such as "no relation entry for relid N" or "failed to build any N-way joins".
- Do not consider parallel-restricted or set-returning functions in an
ORDER BY
expressions when trying to parallelize sorts.- Fix
ALTER DEFAULT PRIVILEGES
to handle duplicate arguments safely.- Several fixes in behavior when
wal_level
is set tominimal
, including when tables are rewritten within a transaction.- Several fixes for
CREATE TABLE LIKE
.- Ensure that allocated disk space for a dropped relation (e.g. a table) is released promptly when a transaction is committed.
- Fix progress reporting for
CLUSTER
.- Fix handling of backslash-escaped multibyte characters in
COPY FROM
.- Fix recently-introduced race conditions in
LISTEN
/NOTIFY
queue handling.- Allow the
jsonb
concatenation operator (||
) to handle all combinations of JSON data types.- Fix WAL-reading logic so that standbys can handle timeline switches correctly. This issue could have shown itself with errors like "requested WAL segment has already been removed".
- Several leak fixes for the
walsender
process around logical decoding and replication.- Ensure that a nonempty value of
krb_server_keyfile
always overrides any setting ofKRB5_KTNAME
in the server environment- Several fixes for GSS encryption support.
- Ensure the
\connect
command allows the use of a password in theconnection_string
argument.- Fix assorted bugs with the
\help
command.- Several fixes for
pg_dump
.- Ensure that
pg_rewind
accounts for all WAL when rewinding a standby server.- Fix memory leak in
contrib/auto_explain
.- Ensure all
postgres_fdw
connections are closed if the a user mapping or foreign server object those connections depend on are dropped.- Fix JIT compilation to be compatible with LLVM 11 and LLVM 12.
This update also contains tzdata release 2021a for DST law changes in Russia (Volgograd zone) and South Sudan, plus historical corrections for Australia, Bahamas, Belize, Bermuda, Ghana, Israel, Kenya, Nigeria, Palestine, Seychelles, and Vanuatu.
Notably, the Australia/Currie zone has been corrected to the point where it is identical to Australia/Hobart.
