Yeah. I had also thought about hard-wiring the WHERE clause, but
there's at least one big objection to that: it fails to cover cases
where there's no need for a flag column because all the entries are
user-provided.
The catalog representation I'd been thinking of was a regclass[] array
for the table names and a text[] array of the same length for the WHERE
clauses. It's slightly ugly but no big deal. There are likely to be
some other array columns in pg_extension before we're done, anyway ---
one I'd been thinking about a bit was OIDs of modules this one depends
on. The current design doesn't cope very well with modules that depend
on other ones.
