No, but you do have to cast an oversize value to oid explicitly to
prevent it from being taken as int4, eg
regression=# select oid = 2444444444 from int4_tbl;
ERROR: dtoi4: integer out of range
regression=# select oid = 2444444444::oid from int4_tbl;
<< works >>
(In releases before about 7.1 you'd have had to single-quote the
literal, too.)
This is one of a whole raft of cases involving undesirable assignment
of types to numeric constants; see past complaints about int4 being used
where int2 or int8 was wanted, numeric vs float8 constants, etc etc.
We're still looking for a promotion rule that does what you want every
time...
