hello - we're excited to be making a change to drop an insane wide column that is pg_toast table > 10T. The question is: what kind of fallout/impact to expect for auto-vacuum and replication after `DROP COLUMN xxx`.
This is a 9.3 cluster w/ multiple of read replicas; > 1k tx/sec; and 2 wal log/sec
thanks in advance!
