Hi,

meanwhile I have received the hint to make postgres use the index via

SET ENABLE_SEQSCAN=FALSE;

which fits perfectly. The execution plan now indicates full use of index.

Nevertheless this is merely a workaround. Maybe the io-costs are configured to cheap.

thanks :-)

People will be wanting the output of EXPLAIN ANALYSE on that query.

They'll also ask whether you've VACUUMed, ANALYSEd and configured your
postgresql.conf correctly.
