Ok. Found the place.
So, there is nothing there. PG_DATA/base/pgsql_tmp is a empty directory.
I've run the query over pg_stat_database view and there is nothing wrong
with pgAdmin III - the information is all there.
I've also run a vacuum freeze analyze, but made no difference.

I believe that statistics are outdated, since there is no temp file at all.

Any tip on that?
