Hm. That comparison is using the wrong datatype, but it appears you only
copied my earlier mistake... Fixed back to 9.4 and in your patch.

Other notes:

* you missed to touch test_decoding's regression test output files.
* None of the docs were touched. catalogs.sgml definitely needs docs about the new columns, and I see no reason to
leavethe examples elsewhere stale.
 

Fixed those and committed it. Thanks for the patch!
