You could probably get away with copying it into some long-term memory
context. Once you've blessed it the record typmod should remain the
same for the rest of the session.
If you're feeling bloody-minded you could remember the pointer returned
by lookup_rowtype_tupdesc(), but that strikes me as assuming too much
about the behavior of typcache.c.
