Thanks for joining the discussion.
I'm only reluctant to do an ANALYZE as part of a perdiodical (hourly)
"check table contents" function.
Such an ANALYZE command is already included in the perdiodical
(nightly) update script which mirrors OpenStreetMap data.
BTW: I've asked before for best parameters over at pgsql-performance
("How to configure a read-only database server?" 19. April 2011) and I
am still happy about any hint.
Yours, Stefan
