Overview

This module manages the installation and configuration of PostgreSQL.

Requirements

  • Chef (no particular version at this time).
  • yum Cookbook.

Attributes

pg::server

Key Type Description Default
['pg']['use_pgdg'] Boolean Determines if Postgres should be installed from the PGDG. false
['pg']['manage_repo'] Boolean Determines if this cookbook should manage the PGDG repo. Only applies if ['pg']['use_pgdg'] is set to true. true
['pg']['pgdg']['version'] String Determines which version of Postgres should be installed/managed. Only applies if ['pg']['use_pgdg'] is set to true. 9.3
['pg']['initdb'] Boolean Determines if the intidb command should be run to do initial population of the database. true
['pg']['initdb_locale'] String Determines the locale to be used by the initdb command on systems running versions less than Postgres 9.4. UTF-8
['pg']['initdb_cmd'] String The command to be run in order to initialise database. Varies based on PG Version, see recipes/server.rb:11-26

The following attributes are used to populate postgresql.conf:

Key Type Description Default
['pg']['config']['server']['port'] Integer Port that Postgres should listen on. 5432
['pg']['config']['server']['max_connections'] Integer Determines the number of connection "slots" that are reserved for connections by PostgreSQL superusers. At most max_connections connections can ever be active simultaneously. Whenever the number of active concurrent connections is at least max_connections minus superuser_reserved_connections, new connections will be accepted only for superusers, and no new replication connections will be accepted. 100
['pg']['config']['server']['shared_buffers'] String Sets the amount of memory the database server uses for shared memory buffers. 32MB
['pg']['config']['server']['logging_collector'] Boolean This parameter enables the logging collector, which is a background process that captures log messages sent to stderr and redirects them into log files. true
['pg']['config']['server']['log_filename'] String When logging_collector is enabled, this parameter sets the file names of the created log files. The value is treated as a strftime pattern, so %-escapes can be used to specify time-varying file names. (Note that if there are any time-zone-dependent %-escapes, the computation is done in the zone specified by log_timezone.) The supported %-escapes are similar to those listed in the Open Group's strftime specification. Note that the system's strftime is not used directly, so platform-specific (nonstandard) extensions do not work. postgresql-%a.log
['pg']['config']['server']['log_truncate_on_rotation'] Boolean When logging_collector is enabled, this parameter will cause PostgreSQL to truncate (overwrite), rather than append to, any existing log file of the same name. true
['pg']['config']['server']['log_rotation_age'] String When logging_collector is enabled, this parameter determines the maximum lifetime of an individual log file. After this many minutes have elapsed, a new log file will be created. Set to zero to disable time-based creation of new log files. 1d
['pg']['config']['server']['log_rotation_size'] Integer When logging_collector is enabled, this parameter determines the maximum size of an individual log file. After this many kilobytes have been emitted into a log file, a new log file will be created. Set to zero to disable size-based creation of new log files. 0
['pg']['config']['server']['log_timezone'] String Sets the time zone used for timestamps written in the server log. Unlike TimeZone, this value is cluster-wide, so that all sessions will report timestamps consistently. UTC
['pg']['config']['server']['datestyle'] String Sets the display format for date and time values, as well as the rules for interpreting ambiguous date input values. iso, mdy
['pg']['config']['server']['timezone'] String Sets the time zone for displaying and interpreting time stamps. UTC
['pg']['config']['server']['lc_messages'] String Sets the language in which messages are displayed. en_US.UTF-8
['pg']['config']['server']['lc_monetary'] String Sets the locale to use for formatting monetary amounts, for example with the to_char family of functions. en_US.UTF-8
['pg']['config']['server']['lc_numeric'] String Sets the locale to use for formatting numbers, for example with the to_char family of functions. en_US.UTF-8
['pg']['config']['server']['lc_time'] String Sets the locale to use for formatting dates and times, for example with the to_char family of functions. en_US.UTF-8
['pg']['config']['server']['default_text_search_config'] String Selects the text search configuration that is used by those variants of the text search functions that do not have an explicit argument specifying the configuration. pg_catalog.english

NOTE: Values that read as on or off in postgresql.conf should be set as true or false respectively.

Finally the following default pg_hba.conf entries are:

default['pg']['config']['hba']['local'] = {
  enabled: true,
  type: 'local',
  database: 'all',
  user: 'postgres',
  address: '',
  method: 'trust'
}
default['pg']['config']['hba']['host'] = {
  enabled: true,
  type: 'host',
  database: 'all',

  enabled: true,
  type: 'host',
  database: 'all',
  user: 'all',
  address: '::1/128',

2016-05-22 (v1.4.0)

Summary

Adds support for pgbouncer.

Features

  • Added pgbouncer support:
    • Install pgbouncer from PGDG.
    • Manage all config files.
    • Manage pgbouncer service.

2016-03-23 (v1.3.1)

Summary

Reload the service when changing HBA config instead of restarting.

Bugfixes

  • Updating config for pg_hba.conf will now cause the Postgres service to reload instead of restart. This change was made as doing a full restart caused undesirable behaviour in some situations.

2016-03-15 (v1.3.0)

Summary

Configurable initdb command.

Features

  • The initdb is now configurable via an attribute. The default remains the same as previous versions.
