I am also using -o -S 2048 now, but I doubt it helps...

Oh, gee. sorry! I slipped with the mouse when cut'n'pasting. The first
statement should be a create view. The view is dropped and created
"on-the-fly" with different where-clauses every time, depending on the
user's search arguments. As I might have said before, I am not the
programmer... I think I would have the view created once, and done
"select from view where..." Maybe that would help, but there is still
a bug in postgres, I guess?

I must take that back, since the select from view only holds two
records... My mistake, again...

in "personer".

Also, I have suddenly become a "very lousy bug reporter", sorry. I forgot the indices:

CREATE  INDEX "personer_fnamn_idx" on "personer" using btree ( lower ("fnamn") "text_ops" );
CREATE UNIQUE INDEX "personer_personid_index" on "personer" using btree ( "personid" "int4_ops" );
CREATE  INDEX "personer_personid_fname_idx" on "personer" using btree ( "personid" "int4_ops", "fnamn" "text_ops" );
