searchPath

The schemas this session's current search_path lists, named as the server reads them: an unquoted name in lower case, $user and pg_temp as they stand.

Read from what the server reported rather than queried for: PostgreSQL 18 announces search_path in ParameterStatus and announces it again whenever it moves, so a hand-written SET search_path mid-session shows up here without a round trip.

This is the setting, not the order a type name is looked up in, which adds pg_catalog ahead of the list unless the list has it and puts the session user's schema in place of $user.
