postgresql-9.1 9.1.6-0ubuntu12.04 source package in Ubuntu

Changelog

postgresql-9.1 (9.1.6-0ubuntu12.04) precise-proposed; urgency=low

  * New upstream bug fix release: (LP: #1055944)
    - Fix persistence marking of shared buffers during WAL replay.
      This mistake can result in buffers not being written out during
      checkpoints, resulting in data corruption if the server later
      crashes without ever having written those buffers. Corruption can
      occur on any server following crash recovery, but it is
      significantly more likely to occur on standby slave servers since
      those perform much more WAL replay. There is a low probability of
      corruption of btree and GIN indexes. There is a much higher
      probability of corruption of table "visibility maps". Fortunately,
      visibility maps are non-critical data in 9.1, so the worst
      consequence of such corruption in 9.1 installations is transient
      inefficiency of vacuuming. Table data proper cannot be corrupted by
      this bug.
      While no index corruption due to this bug is known to have occurred
      in the field, as a precautionary measure it is recommended that
      production installations "REINDEX" all btree and GIN indexes at a
      convenient time after upgrading to 9.1.6.
      Also, if you intend to do an in-place upgrade to 9.2.X, before
      doing so it is recommended to perform a "VACUUM" of all tables
      while having vacuum_freeze_table_age set to zero. This will ensure
      that any lingering wrong data in the visibility maps is corrected
      before 9.2.X can depend on it. vacuum_cost_delay can be adjusted to
      reduce the performance impact of vacuuming, while causing it to
      take longer to finish.
    - See HISTORY/changelog.gz for the other bug fixes.

libecpg-compat3: older version of run-time library for ECPG programs

 The libecpg_compat shared library is used by programs built with ecpg.
 (Embedded PostgreSQL for C).
 .
 PostgreSQL is an object-relational SQL database management system.

libecpg-dev: development files for ECPG (Embedded PostgreSQL for C)

 This package contains the necessary files to build ECPG (Embedded
 PostgreSQL for C) programs. It includes the development libraries
 and the preprocessor program ecpg.
 .
 PostgreSQL is an object-relational SQL database management system.
 .
 Install this package if you want to write C programs with SQL statements
 embedded in them (rather than run by an external process).

libecpg6: run-time library for ECPG programs

 The libecpg shared library is used by programs built with ECPG
 (Embedded PostgreSQL for C).
 .
 PostgreSQL is an object-relational SQL database management system.

libpgtypes3: shared library libpgtypes for PostgreSQL 9.1

 The libpgtypes shared library is used by programs built with ecpg.
 (Embedded PostgreSQL for C).
 .
 PostgreSQL is an object-relational SQL database management system.

libpq-dev: header files for libpq5 (PostgreSQL library)

 Header files and static library for compiling C programs to link
 with the libpq library in order to communicate with a PostgreSQL
 database backend.
 .
 PostgreSQL is an object-relational SQL database management system.

libpq5: PostgreSQL C client library

 libpq is a C library that enables user programs to communicate with
 the PostgreSQL database server. The server can be on another machine
 and accessed through TCP/IP. This version of libpq is compatible
 with servers from PostgreSQL 8.2 or later.
 .
 This package contains the run-time library, needed by packages using
 libpq.
 .
 PostgreSQL is an object-relational SQL database management system.

postgresql-9.1: object-relational SQL database, version 9.1 server

 PostgreSQL is a fully featured object-relational database management
 system. It supports a large part of the SQL standard and is designed
 to be extensible by users in many aspects. Some of the features are:
 ACID transactions, foreign keys, views, sequences, subqueries,
 triggers, user-defined types and functions, outer joins, multiversion
 concurrency control. Graphical user interfaces and bindings for many
 programming languages are available as well.
 .
 This package provides the database server for PostgreSQL 9.1. Servers
 for other major release versions can be installed simultaneously and
 are coordinated by the postgresql-common package. A package providing
 ident-server is needed if you want to authenticate remote connections
 with identd.

postgresql-9.1-dbg: debug symbols for postgresql-9.1

 PostgreSQL is a fully featured object-relational database management
 system. It supports a large part of the SQL standard and is designed
 to be extensible by users in many aspects. Some of the features are:
 ACID transactions, foreign keys, views, sequences, subqueries,
 triggers, user-defined types and functions, outer joins, multiversion
 concurrency control. Graphical user interfaces and bindings for many

 .
 This package provides detached debugging symbols for PostgreSQL 9.1.

postgresql-client-9.1: front-end programs for PostgreSQL 9.1

 This package contains client and administrative programs for
 PostgreSQL: these are the interactive terminal client psql and
 programs for creating and removing users and databases.
 .
 This is the client package for PostgreSQL 9.1. If you install
 PostgreSQL 9.1 on a standalone machine, you need the server package
 postgresql-9.1, too. On a network, you can install this package on
 many client machines, while the server package may be installed on
 only one machine.
 ..

postgresql-contrib-9.1: additional facilities for PostgreSQL

 The PostgreSQL contrib package provides several additional features
 for the PostgreSQL database. This version is built to work with the
 server package postgresql-9.1. contrib often serves as a testbed for
 features before they are adopted into PostgreSQL proper:
 .
  adminpack - File and log manipulation routines, used by pgAdmin
  btree_gist - B-Tree indexing using GiST (Generalised Search Tree)
  chkpass - An auto-encrypted password datatype
  cube - Multidimensional-cube datatype (GiST indexing example)
  dblink - Functions to return results from a remote database
  earthdistance - Operator for computing the distance (in miles) between
                   two points on the earth's surface
  fuzzystrmatch - Levenshtein, metaphone, and soundex fuzzy string matching
  hstore - Store (key, value) pairs
  intagg - Integer aggregator/enumerator
  _int - Index support for arrays of int4, using GiST (benchmark
                   needs the libdbd-pg-perl package)
  isn - type extensions for ISBN, ISSN, ISMN, EAN13 product numbers
  lo - Large Object maintenance
  ltree - Tree-like data structures
  oid2name - Maps OIDs to table names
