Have you tried writing the query to filter on gd.id_gd rather than g.id_gd? I am not sure if the query planner will realize that it can replace g.id_gd with gd.id_gd in the where clause.
select g.gd_index, gd.full_name from gd g join gd_data gd on (g.id_gd = gd.id_gd) where gd.id_gd_data = 1111 OR gd.id_gd = 1111; -- Andreas Karlsson -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
