Requirements (on host that executes module)

  • psycopg2

Options

parameter required default choices comments
encoding
 no
Encoding of the database
lc_collate
 no
Collation order (LC_COLLATE) to use in the database. Must match collation order of template database unless template0 is used as template.
lc_ctype
 no
Character classification (LC_CTYPE) to use in the database (e.g. lower, upper, ...) Must match LC_CTYPE of template database unless template0 is used as template.
login_host
 no
Host running the database
login_password
 no
The password used to authenticate with
login_unix_socket
 no
Path to a Unix domain socket for local connections
login_user
 no postgres
The username used to authenticate with
name
 yes
name of the database to add or remove
owner
 no
Name of the role to set as owner of the database
port
 no 5432
Database port to connect to.
ssl_mode
(added in 2.3)
 no prefer
  • disable
  • allow
  • prefer
  • require
  • verify-ca
  • verify-full
Determines whether or with what priority a secure SSL TCP/IP connection will be negotiated with the server.
See https://www.postgresql.org/docs/current/static/libpq-ssl.html for more information on the modes.
Default of prefer matches libpq default.
ssl_rootcert
(added in 2.3)
 no
Specifies the name of a file containing SSL certificate authority (CA) certificate(s).
If the file exists, the server's certificate will be verified to be signed by one of these authorities.
state
 no present
  • present
  • absent
  • dump
  • restore
The database state. present implies that the database should be created if necessary. absent implies that the database should be removed if present. dump requires a target definition to which the database will be backed up. (Added in 2.4) restore also requires a target definition from which the database will be restored. (Added in 2.4) The format of the backup will be detected based on the target name. Supported compression formats for dump and restore are: .bz2, .gz, and .xz Supported formats for dump and restore are: .sql and .tar
target
(added in 2.4)
 no
File to back up or restore from. Used when state is "dump" or "restore"
target_opts
(added in 2.4)
 no
Further arguments for pg_dump or pg_restore. Used when state is "dump" or "restore"
template
 no
Template used to create the database

Examples

# Create a new database with name "acme"
- postgresql_db:
    name: acme

# Create a new database with name "acme" and specific encoding and locale
# settings. If a template different from "template0" is specified, encoding
# and locale settings must match those of the template.
- postgresql_db:
    name: acme
    encoding: UTF-8
    lc_collate: de_DE.UTF-8
    lc_ctype: de_DE.UTF-8
    template: template0

# Dump an existing database to a file
- postgresql_db:
    name: acme
    state: dump
    target: /tmp/acme.sql

# Dump an existing database to a file (with compression)
- postgresql_db:
    name: acme
    state: dump
    target: /tmp/acme.sql.gz

# Dump a single schema for an existing database
- postgresql_db:
    name: acme
    state: dump
    target: /tmp/acme.sql
    target_opts: "-n public"

Notes

Note

  • The default authentication assumes that you are either logging in as or sudo’ing to the postgres account on the host.
  • This module uses psycopg2, a Python PostgreSQL database adapter. You must ensure that psycopg2 is installed on the host before using this module. If the remote host is the PostgreSQL server (which is the default case), then PostgreSQL must also be installed on the remote host. For Ubuntu-based systems, install the postgresql, libpq-dev, and python-psycopg2 packages on the remote host before using this module.
  • The ssl_rootcert parameter requires at least Postgres version 8.4 and psycopg2 version 2.4.3.

Status

This module is flagged as stableinterface which means that the maintainers for this module guarantee that no backward incompatible interface changes will be made.
