Hello, We noticed that after upgrading to 7.1beta[245] the execution time for some often used queries went up by a factor of 2 or more. Considering the early beta state I was not alarmed. But since I noticed that yesterday's snapshot still has the problem, I'd really like to tell you about it. Here is one of the queries, it takes about half a second on our computer (PII 233 with 256MB RAM) to execute and returns typically 1-4 rows via two index scans with high selectivity. So it looks to me that planning time outwages execution time by far. 7.0 took about 0.15 seconds (which is still much). Here is the query: explain verbose select gaenge , s . artikelid , text from schaertabelle s , extartbez e where maschine = int2(109) and schaerdatum = '2001-01-13' and s . artikelid = e . artikelid and extartbezid = 1 and bezkomptype = 0 order by text limit 10; And the plan for 7.0 and 7.1 (attached). The data and schema is accessible via http://home.wtal.de/petig/pg_test.sql.gz If you omit 'int2(' the index scan collapses into a sequential scan. (Well known problem with int2 indices) Christof Oh, I'll attach the schema, too. So if you just want to take a look at the table definition you don't have to download the data.
