We have a GUI that let user browser through the record page by page at about 25 records a time. (Don't ask me why but we have to have this GUI). This translates to something like

  select count(*) from table   <-- to give feedback about the DB size
  select * from table order by date limit 25 offset 0


Heh, sounds like phpPgAdmin...I really should do something about that.

Tables seems properly indexed, with vacuum and analyze ran regularly. Still this very basic SQLs takes up to a minute run.

Yes, COUNT(*) on a large table is always slow in PostgreSQL. Search the mailing lists for countless discussions about it.
