Yeah, that's the built-in "text || text" operator. The question is where
is the "hstore || hstore" operator added by the hstore extension. If
you're not seeing that in \do output, then it's not in your search path.

Actually, it might be better to try "\do *.||", which should show all
operators named || regardless of which schema they are in and whether
that schema is in your path.
