Hi Razvan,

Just to add to what Tom has already said, this is most certainly because
of your tsearch/gist usage. Check the Tsearch2 site [1] for a lot of
interesting documentation on Tsearch2.
For a quite nice howto on backups and restores of databases with
Tsearch2 see the Tsearch2 Intro document [2]

There is actually now a patch [3] to tsearch (only for 7.4 though) which
is supposed to improve dumping and reloading of tsearch2 databases.
