I do not think it's a good idea to define xid and int as
binary-compatible. If it is a good idea then you did it wrong
--- IS_BINARY_COMPATIBLE needs to test for both directions.
But what I'd suggest is to undo the IS_BINARY_COMPATIBLE change
and instead add another pg_operator entry that accepts xid = int4,
mapping it to xideq. That gets the job done without opening up
a morass of binary-compatibility issues.
