Oops, looks like I missed your question. Sorry for so long delay.
User might want to compress only megabyte+ records, there's nothing wrong with it. WAL record itself is capped by 1Gb
(XLogRecordMaxSize),I do not see a reason to restrict wal_compression_threshold by lower value.
PFA rebased version.
