Yeah, that's probably OK for tab-completion.
It's a shame though that pg_view_is_updatable() and
pg_view_is_insertable() are not really useful for identifying
potentially updatable views (e.g., consider an auto-updatable view on
top of a trigger-updatable view). I'm left wondering if I
misinterpreted the SQL standard's intentions when separating out the
concepts of "updatable" and "trigger updatable". It seems like it
would have been more useful to have "trigger updatable" imply
"updatable".
