Notes

Note

  • 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.
