The center point of this isn't missing ANALYZE, but so was used PostgreSQL
on windows. There is propably bug in test no. 8. I hadn't this problem on
Linux. Others PostgreSQL is comparable with Firebird. If you look on this
test - it's only simple SELECT or max. join two tables. There isn't space
for PostgreSQL force. When I did test for self join 4 tables, PostgreSQL was
better then MySQL and Firebird
