pgsql: Weaken type-OID-matching checks in array_recv and record_recv.

Weaken type-OID-matching checks in array_recv and record_recv.

Rather than always insisting on an exact match of the type OID in the
data to the element type or column type we expect, complain only when
both OIDs fall within the manually-assigned range. This acknowledges
the reality that user-defined types don't have stable OIDs, while
still preserving some of the mistake-detection value of the old test.

(It's not entirely clear whether to error if one OID is manually
assigned and the other isn't. But perhaps that case could arise in
cross-version cases where a former extension type has been imported
into core, so I let it pass.)

This change allows us to remove the prohibition on binary transfer
of user-defined arrays and composites in the recently-landed support
for binary logical replication (commit 9de77b545). We can just
unconditionally drop that check, since if the client has asked for
binary transfer it must be >= v14 and must have this change.
