I recreated the table, so I think there is not necessary to vacuum it
(it takes unbelieveable amount of time); maybe when I'm filling the
table by sending a lot of INSERT queries I should sometimes between
inserts do a vacuum ? It looks strange for me.

And many thanks for your help; I was thinking about dropping indexes and
trigger, but It's impossible. Imagine this is not just a series of
insert queries, the process I'm using is (simplicied): For each dbase
record (the catalogue from the music label) to look-up if exist and if
so, update; if no, insert. So I can't drop indexes which are needed by
look-up function; nor can't drop trigger because it tracks inserts /
updates of my table.
I'm testing to group inserts / updates to blocks enclosed with
transaction BEGIN; END;, but it now looks that it will help only little.

PS I plan to rewrite the whole thing to Mysql (even it's no triggers, it
will be harder but possible of course) and to report the result here if
will be interesting)
