Hmm, maybe I didn't explain clearly enough. I meant that if the
argument is a regclass for example, to pass it in the TG_ARGV list as
the OID in *string form*.
That way trigger arguments stay a list of strings, yet the whole thing
is schema safe because when trigger body casts the string back to a
regclass, it gets exactly what was passed.
Hope this makes more sense,
