As Tom already mentioned, this is per-DB. So you have to aggregate the
privileges yourself,
i.e. connect to any DB, lookup all databases the user can connect to, then
connect to each DB
in turn (possibly in parallel using several concurrent connections) to get
the privs in that DB.
This presumes the user doing the lookup can connect to at least the DBs
that user's has access to.
The query below should get you started on the first part. Just move the
can-CONNECT test
to the WHERE-clause instead of the SELECT-clause, and change session_user.
--DD
SELECT datname, datdba::regrole::text as owner,
has_database_privilege(session_user, datname, 'CONNECT') as
can_connect,
has_database_privilege(session_user, datname, 'CREATE') as
can_create
FROM pg_database
WHERE datistemplate = false
