Add or remove PostgreSQL databases from a remote host.
- name: Create a new database with name "acme" postgresql_db: name: acme
# Note: If a template different from "template0" is specified, encoding and locale settings must match those of the template. - name: Create a new database with name "acme" and specific encoding and locale # settings. postgresql_db: name: acme encoding: UTF-8 lc_collate: de_DE.UTF-8 lc_ctype: de_DE.UTF-8 template: template0
# Note: Default limit for the number of concurrent connections to a specific database is "-1", which means "unlimited" - name: Create a new database with name "acme" which has a limit of 100 concurrent connections postgresql_db: name: acme conn_limit: "100"
- name: Dump an existing database to a file postgresql_db: name: acme state: dump target: /tmp/acme.sql
- name: Dump an existing database to a file excluding the test table postgresql_db: name: acme state: dump target: /tmp/acme.sql dump_extra_args: --exclude-table=test
- name: Dump an existing database to a file (with compression) postgresql_db: name: acme state: dump target: /tmp/acme.sql.gz
- name: Dump a single schema for an existing database postgresql_db: name: acme state: dump target: /tmp/acme.sql target_opts: "-n public"
# Note: In the example below, if database foo exists and has another tablespace # the tablespace will be changed to foo. Access to the database will be locked # until the copying of database files is finished. - name: Create a new database called foo in tablespace bar postgresql_db: name: foo tablespace: bar
name: aliases: - db description: - Name of the database to add or remove required: true type: str port: aliases: - login_port default: 5432 description: - Database port to connect (if needed) type: int owner: description: - Name of the role to set as owner of the database type: str state: choices: - absent - dump - present - restore default: present description: - The database state. - C(present) implies that the database should be created if necessary. - C(absent) implies that the database should be removed if present. - C(dump) requires a target definition to which the database will be backed up. (Added in Ansible 2.4) Note that in some PostgreSQL versions of pg_dump, which is an embedded PostgreSQL utility and is used by the module, returns rc 0 even when errors occurred (e.g. the connection is forbidden by pg_hba.conf, etc.), so the module returns changed=True but the dump has not actually been done. Please, be sure that your version of pg_dump returns rc 1 in this case. - C(restore) also requires a target definition from which the database will be restored. (Added in Ansible 2.4) - The format of the backup will be detected based on the target name. - Supported compression formats for dump and restore include C(.pgc), C(.bz2), C(.gz) and C(.xz) - Supported formats for dump and restore include C(.sql) and C(.tar) type: str target: description: - File to back up or restore from. - Used when I(state) is C(dump) or C(restore). type: path ca_cert: aliases: - ssl_rootcert description: - 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. type: str encoding: description: - Encoding of the database type: str lc_ctype: description: - Character classification (LC_CTYPE) to use in the database (e.g. lower, upper, ...) Must match LC_CTYPE of template database unless C(template0) is used as template. type: str ssl_mode: choices: - allow - disable - prefer - require - verify-ca - verify-full default: prefer description: - Determines whether or with what priority a secure SSL TCP/IP connection will be negotiated with the server. - See U(https://www.postgresql.org/docs/current/static/libpq-ssl.html) for more information on the modes. - Default of C(prefer) matches libpq default. type: str template: description: - Template used to create the database type: str conn_limit: description: - Specifies the database connection limit. type: str lc_collate: description: - Collation order (LC_COLLATE) to use in the database. Must match collation order of template database unless C(template0) is used as template. type: str login_host: description: - Host running the database. type: str login_user: default: postgres description: - The username used to authenticate with. type: str tablespace: description: - The tablespace to set for the database U(https://www.postgresql.org/docs/current/sql-alterdatabase.html). - If you want to move the database back to the default tablespace, explicitly set this to pg_default. type: path target_opts: description: - Further arguments for pg_dump or pg_restore. - Used when I(state) is C(dump) or C(restore). type: str session_role: description: - Switch to session_role after connecting. The specified session_role must be a role that the current login_user is a member of. - Permissions checking for SQL commands is carried out as though the session_role were the one that had logged in originally. type: str login_password: description: - The password used to authenticate with. type: str maintenance_db: default: postgres description: - The value specifies the initial database (which is also called as maintenance DB) that Ansible connects to. type: str dump_extra_args: description: - Provides additional arguments when I(state) is C(dump). - Cannot be used with dump-file-format-related arguments like ``--format=d``. type: str login_unix_socket: description: - Path to a Unix domain socket for local connections. type: str
