With PostgreSQL, a the agent can simply daemonize and talk to the
Postmaster using libpq and proper HBA. Everything in pg_catalog.* and
information_schema.* is already quantified in SQL data structures:

postgres=# \d pg_catalog.pg_tables;
View "pg_catalog.pg_tables"

Column | Type | Modifiers
-------------+---------+-----------
schemaname | name |
tablename | name |
tableowner | name |
tablespace | name |
hasindexes | boolean |
hasrules | boolean |
hastriggers | boolean |

postgres=# SELECT * from pg_catalog.pg_database limit 2;
datname | datdba | encoding | datistemplate | datallowconn | datconnlimit | datlastsysoid | datfrozenxid | dattablespace | datconfig | datacl
----------+--------+----------+---------------+--------------+--------------+---------------+--------------+---------------+-----------+--------
postgres | 10 | 0 | f | t | -1 | 10818 | 34352041 | 1663 | |
nagios | 17056 | 0 | f | t | -1 | 10818 | 34352146 | 1663 | |
