DESCRIPTION: Fix performance issue when distributing a table that
depends on an extension
When the database contains many objects this function would show up in
profiles because it was doing a sequence scan on pg_depend. And with
many objects pg_depend can get very large.
This starts using an index scan to only look for rows containing FDWs,
of which there are expected to be very few (often even zero).
