If tablename exists in search_path then it will not show the schemaname. Its
normal behavior.
You can create function something like given below for consistent names and can
use it:
CREATE OR REPLACE FUNCTION pg_get_relname(oid) RETURNS text
as
$$
SELECT n.nspname||'.'|| c.relname as "Name" FROM pg_catalog.pg_class c
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relkind='r' and c.oid=$1
$$ language sql;
