Subject: pgsql: REPACK CONCURRENTLY: fix processing of toasted tuples

Message-ID: <E1wIZLC-003VlP-1T@gemulon.postgresql.org> (raw)
REPACK CONCURRENTLY: fix processing of toasted tuples
In order to process tuples inserted or updated while REPACK executes, we
write those tuples to disk and later restore them; however, some forms
of toasted tuples were not being processed correctly. Fix that.
Also expand the tests a bit for better coverage.
