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
, andpython-psycopg2
packages on the remote host before using this module. - The default authentication assumes that you are either logging in as or sudo’ing to the
postgres
account on the host. - To avoid “Peer authentication failed for user postgres” error, use postgres user as a become_user.
- 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 ca_cert parameter requires at least Postgres version 8.4 and psycopg2 version 2.4.3.
