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.
  • The ca_cert parameter requires at least Postgres version 8.4 and psycopg2 version 2.4.3.
