So far as I can see offhand, the only way you'd get that error message
is if to_tsquery were declared to take OID not regconfig as its first
argument.

contrib/tsearch2 does provide a "to_tsquery(oid, text)" function ... I'm
not sure why offhand, nor how come that's managing to show up in front
of the standard definition in your search path. Try dropping that.
(Another question is why it wasn't failing already in your 8.3 DB.
The behavior shouldn't be any different AFAICS. Are you sure you
are using the same search_path as before?)
