improvement of Postgres-specific support in Ansible

Hello all !

There is the Ansible postgresql working group https://github.com/ansible/community/wiki/PostgreSQL
that was created a couple of months ago (thanks Ansible engineers Dag Wieers (@dagwieers) and John R. Barcker (@gundalow) for support).

Over the last 3 months we've added 4 new modules to 6 existing, these are:
postgresql_idx
postgresql_ping
postgresql_query
postgresql_tablespace
 
I've also completed 4 new modules that waiting for the second approval or reviews:
postgresql_facts ( good reviewed, has shipit, needs the second one ) https://github.com/ansible/ansible/pull/51164
postgresql_set ( good reviewed, has shipit, needs the second one ) https://github.com/ansible/ansible/pull/51875
postgresql_table https://github.com/ansible/ansible/pull/52077
postgresql_membership https://github.com/ansible/ansible/pull/53733

Would be better to see them merged until 21 March Ansible ver. 2.8 feature freeze.
 
Who's interested in significant improvement of Postgres-specific support, uses Ansible, and familiar with Python,
please, look at the pull requests above and approve them by writing shipit to a new comment or give your opinion how to make them better.
