On the same server, <code>statement_timeout</code> differs between two databases, and neither value is in a file. In <a href="https://www.postgresql.org/">PostgreSQL</a>, <code>ALTER ROLE ... SET</code> and <code>ALTER DATABASE ... SET</code> store their defaults in the <a href="https://www.postgresql.org/docs/current/catalog-pg-db-role-setting.html"><code>pg_db_role_setting</code></a> catalog, and those defaults <a href="https://www.postgresql.org/docs/current/sql-alterrole.html">override <code>postgresql.conf</code></a> when a session starts. The query below lists every override in the cluster by role and database.</p>
