Have you done this:

http://www.postgresql.org/docs/9.2/interactive/sql-alterrole.html

ALTER ROLE name [ IN DATABASE database_name ] SET
configuration_parameter { TO | = } { value | DEFAULT }


To check:

http://www.postgresql.org/docs/9.2/interactive/app-psql.html

\drds [ role-pattern [ database-pattern ] ]
Lists defined configuration settings. These settings can be
role-specific, database-specific, or both. role-pattern and
database-pattern are used to select specific roles and databases to
list, respectively. If omitted, or if * is specified, all settings are
listed, including those not role-specific or database-specific,
respectively.

The ALTER ROLE and ALTER DATABASE commands are used to define per-role
and per-database configuration settings.
