Branch: CURRENT, Version: 9.5.13, Package name: postgresql95-docs-9.5.13, Maintainer: adam

PostgreSQL is a robust, next-generation, Object-Relational DBMS (ORDBMS),
derived from the Berkeley Postgres database management system. While
PostgreSQL retains the powerful object-relational data model, rich data types
and easy extensibility of Postgres, it replaces the PostQuel query language
with an extended subset of SQL.

PostgreSQL is free and the complete source is available.

This package contains the database documentation.

SECURITY ISSUES
One security vulnerability has been closed by this release:

CVE-2018-1115: Too-permissive access control list on function pg_logfile_rotate()
Please see the "Updating" section below for post-update steps.

BUG FIXES AND IMPROVEMENTS
This update also fixes over 50 bugs reported in the last several months. Some of \ 
these issues affect only version 10, but many affect all supported versions.

These fixes include:
Fix incorrect volatility and parallel-safety markings on several built-in \ 
functions to ensure correct query planning optimizations
Several fixes for partitioning, including potential crashes as well as allowing \ 
TRUE and FALSE to be used as partition bounds
Fix where a new TOAST value could be assigned to a dead-but-not-yet-vacuumed \ 
TOAST OID, which would result in an error similar to "unexpected chunk \ 
number 0 (expected 1) for toast value nnnnn"
Fix "CREATE TABLE ... LIKE" with bigint identity columns on 32-bit \ 
platforms
Fix memory leak within the runtime of a query that repeatedly executes hash joins
Several crash fixes around queries using GROUPING SET
Avoid failure if a query-cancel or session-termination interrupt occurs while \ 
committing a prepared transaction
Reduce locking during autovacuum worker scheduling, which prevents loss of \ 
potential worker concurrency
Fix possible slow execution of REFRESH MATERIALIZED VIEW CONCURRENTLY
Several fixes around query plans that use "index-only" scans
Avoid deadlocks in concurrent CREATE INDEX CONCURRENTLY commands that are run \ 
under SERIALIZABLE or REPEATABLE READ transaction isolation
Several fixes for SP-GiST indexes, including one collation-aware searches on \ 
text columns
Fixes related to counting the number of tuples in partial GiST, SP-GiST, and \ 
Bloom indexes
Several fixes for logical decoding and replication
Fix misquoting of values for list-valued GUC variables (e.g. \ 
local_preload_libraries, session_preload_libraries, shared_preload_libraries, \ 
temp_tablespaces) in dumps
Several fixes for pg_stat_activity
Several fixes for ecpg
Fix for pg_recvlogical to ensure compatibility with PostgreSQL versions released \ 
before 10
Several fixes for pg_rewind

postgresqlNN: updated to 10.3, 9.6.8, 9.5.12, 9.4.17, 9.3.22

PostgreSQL 10.3, 9.6.8, 9.5.12, 9.4.17, and 9.3.22:
The purpose of this release is to address CVE-2018-1058, which describes how a \ 
user can create like-named objects in different schemas that can change the \ 
behavior of other users' queries and cause unexpected or malicious behavior, \ 
also known as a "trojan-horse" attack. Most of this release centers \ 
around added documentation that describes the issue and how to take steps to \ 
mitigate the impact on PostgreSQL databases.

Log message:
postgresql: updated to 10.2, 9.6.7, 9.5.11, 9.4.16, and 9.3.21

This release fixes two security issues. This release also fixes issues with \ 
VACUUM, GIN indexes, and hash indexes that could lead to data corruption, as \ 
well as fixes for using parallel queries and logical replication.

Security Issues
* CVE-2018-1052: Fix the processing of partition keys containing multiple expressions
* CVE-2018-1053: Ensure that all temporary files made with \ 
"pg_upgrade" are non-world-readable

Bug Fixes and Improvements
* Fix crash and potential disclosure of backend memory when processing partition \ 
keys containing multiple expressions
* Fix potential disclosure of temporary files containing database passwords \ 
created by pg_upgrade by not allowing these files to be world-accessible
* Fix cases where VACUUM would not remove dead rows if they were updated while \ 
"key-share" locked, leading to potential data corruption
* Fix for GIN indexes to prevent bloat by ensuring the pending-insertions list \ 
is cleaned up by VACUUM
* Fix potential index corruption with hash indexes due to failure to mark \ 
metapages as dirty
* Fix several potential crash scenarios for parallel queries, including when a \ 
bitmap heap scan cannot allocate memory
* Fix several potential hang-ups in parallel queries, including when a parallel \ 
worker fails to start
* Fix collection of EXPLAIN statistics from parallel workers
* Prevent fake deadlock failures when multiple sessions are running CREATE INDEX \ 
CONCURRENTLY
* Fix for trigger behavior when using logical replication
* Several fixes for "walsender" functionality to improve stability as \ 
well as visibility into the replication process
* Fix logical decoding to correctly clean up disk files for crashed transactions
* Several fixes for identity columns, including disallowing identity columns on \ 
tables derived from composite types and partitions
* Fix handling of list partitioning constraints for partition keys of boolean \ 
and array types
* Fix incorrectly generated plans for UPDATE and DELETE queries when a table has \ 
a mix of inherited regular and foreign child tables
* Fix incorrect query results from cases involving GROUPING SETS when used with \ 
flattened subqueries
* Fix UNION/INTERSECT/EXCEPT over zero columns, e.g. "SELECT UNION SELECT;"
* Several fixes for subqueries within a LATERAL subquery
* Several improvements for query planning estimation
* Allow a client that supports SCRAM channel binding, such as a future version \ 
of PostgreSQL or libpq, to connect to a PostgreSQL 10 server
* Fix sample INSTR() functions used to help transition from Oracle(r) PL/SQL to \ 
PostgreSQL PL/pgSQL to correctly match Oracle functional behavior
* Fix pg_dump to make permissions (ACL), security label, and comment entries \ 
reliably identifiable in archive outputs
* Modify behavior for contrib/cube's "cube ~> int" operator to make \ 
it compatible with KNN search. This is a backwards incompatible change and any \ 
expression indexes or materialized views using this operator will need to be \ 
reindexed and refreshed, respectively.
* Several fixes in contrib/postgres_fdw to prevent query planner errors
* Added modern examples of auto-start scripts for PostgreSQL on macOS in the \ 
contrib/start-scripts/macos directory
* Several fixes for Windows, including postmaster startup and compatibility with \ 
libperl
* Spinlock fixes and support for Motorola 68K and 88K architectures

Log message:
postgresql: updated to the latest

The PostgreSQL Global Development Group has released an update to all supported \ 
versions of our database system, including 10.1, 9.6.6, 9.5.10, 9.4.15, 9.3.20, \ 
and 9.2.24. This release fixes three security issues. This release also fixes \ 
issues found in BRIN indexing, logical replication and other bugs reported over \ 
the past three months.

All users using the affected versions of PostgreSQL should update as soon as \ 
possible. If you use BRIN indexes or contrib/start-scripts, please see the \ 
release notes for additional post-upgrade steps.

Security Issues

Three security vulnerabilities have been fixed by this release:

CVE-2017-12172: Start scripts permit database administrator to modify root-owned \ 
files
CVE-2017-15098: Memory disclosure in JSON functions
CVE-2017-15099: INSERT ... ON CONFLICT DO UPDATE fails to enforce SELECT privileges

Bug Fixes and Improvements

This update also fixes a number of bugs reported in the last few months. Some of \ 
these issues affect only version 10, but many affect all supported versions:

Fix a race condition in BRIN indexing that could cause some rows to not be \ 
included in the indexing.
Fix crash when logical decoding is invoked from a PL language function.
Several fixes for logical replication.
Restored behavior for CTEs attached to INSERT/UPDATE/DELETE statements to \ 
pre-version 10.
Prevent low-probability crash in processing of nested trigger firings.
Do not evaluate an aggregate function's argument expressions when the conditions \ 
in the FILTER clause evaluate to FALSE. This complies with SQL-standard \ 
behavior.
Fix incorrect query results when multiple GROUPING SETS columns contain the same \ 
simple variable.
Fix memory leak over the lifespan of a query when evaluating a set-returning \ 
function from the target list in a SELECT.
Several fixes for parallel query execution, including fixing a crash in the \ 
parallel execution of certain queries that contain a certain type of bitmap \ 
scan.
Fix json_build_array(), json_build_object(), jsonb_build_array(), and \ 
jsonb_build_object() to handle explicit VARIADIC arguments correctly.
Prevent infinite float values from being casted to the numeric type.
Fix autovacuum's “work item” logic to prevent possible crashes and silent \ 
loss of work items.
Several fixes for VIEWs around adding columns to the end of a view.
Fix for hashability detection of range data types that are created by a user.
Improvements on using extended statistics on columns for the purposes of query \ 
planning.
Prevent idle_in_transaction_session_timeout from being ignored when a \ 
statement_timeout occurred earlier.
Fix low-probability loss of NOTIFY messages due more than 2 billion transactions \ 
processing before any queries are executed in the session.
Several file system interaction fixes.
Correctly restore the umask setting when file creation fails in COPY or lo_export().
Fix pg_dump to ensure that it emits GRANT commands in a valid order.
Fix pg_basebackup's matching of tablespace paths to canonicalize both paths \ 
before comparing to help improve Windows compatibility.
Fix libpq to not require user's home directory to exist when trying to read the \ 
"~/.pgpass" file.
Several fixes for ecpg.
