Hmm ... what do you get from
select oid from pg_class where relname = 'nominativi';
select relname from pg_class where oid = 201327173;
If the first returns 201327173 while the second doesn't return anything,
then I'd wonder about corruption of pg_class's OID index. REINDEXing it
might help. I don't remember whether 7.4 makes you use a standalone
backend to reindex system catalogs --- see its REINDEX man page for
details.
