Hi,
il we need to consult the options for a specific role, we can find that
information in the pg_roles table. But options for a database is not in
pg_database, there is no field datconfig. Is there a reason for that?
Regards,
Fabrice

The reason is that "pg_roles" is not a table, but a view.
The table that stores the roles is "pg_authid", and that catalog doesn't
have a "rolconfig" column either.
The parameters set for roles and/or databases are stored in "pg_db_role_setting",
and the values in "pg_roles.rolconfig" are taken from there.
Look at "\d+ pg_roles" to see for yourself.
Yours,
Laurenz Albe

Yeah, options are stored separately to support having options that vary
per user and per database. See \drds, especially under psql -E.
