Definitely. But wouldn't three (or six) extra `=' operators be the road of
least resistance or clearest separation? Not sure.

Certain elements around these parts actively advocate using oids for keys
or even unsigned numbers (*shudder*). I wouldn't be so sure about this
statement at all.
One thing to keep in mind in any case is that oids might not be int4-like
forever, eventually we might want int8, or the unsigned version thereof.
