Check interrupts during logical decoding more frequently. When reading large amounts of preexisting WAL during logical decoding using the SQL interface we possibly could fail to check interrupts in due time. Similarly the same could happen on systems with a very high WAL volume while creating a new logical replication slot, independent of the used interface.
Previously these checks where only performed in xlogreader's read_page callbacks, while waiting for new WAL to be produced. That's not sufficient though, if there's never a need to wait. Walsender's send loop already contains a interrupt check. Backpatch to 9.4 where the logical decoding feature was introduced.
