Dear Heikki, thank you for your valuable feedback. Regarding your questions: It gradually slower every day. The database size is increasing only slightly over time. I will try your hint regarding CLUSTERING. The difference in effect of VACUUM FULL in version 9.0 sounds very interesting. I will discuss the update to version 9.0 with my colleague. Any further idea or feedback is much appreciated.
Index bloat could be a factor too - performing a regular REINDEX on the relevant tables could be worth a try.
