Firebird 1.5.3 X Postgresql 8.1.3 (linux and windows)

Hello,
continuing the saga,
http://archives.postgresql.org/pgsql-performance/2006-04/msg00558.php ,
my coleague created a test database with fake data (see below).

The above archived message contains the the timings of firebird and postgresql.
The weird problem are the 2 queries that firebird executes in less than 2
seconds and postgresql took almost half hour to complete at 100% cpu.


you could download the test database at the address below. It is a 128 kpbs
adsl connection.
