+1
Also, current value for LOGICALREP_IS_COMMIT is 1, but previous code expected
flags to be zero, so this way logical replication between postgres-10 and
postgres-with-2pc-decoding will be broken. So ISTM it’s better to set
LOGICALREP_IS_COMMIT to zero and change flags checking rules to accommodate that.
