This is a bug in whatever generated that query (if it was pgAdmin 4,
you should complain on the pgadmin lists). Probably, it printed an
OID value as a signed integer when it should have printed it as an
unsigned integer. That's an easy mistake that doesn't show up
until your database gets past 2^31 OIDs consumed :-(.

The server error message is correct as far as it goes: there's no minus
operator for the OID type. Since OID is unsigned, it wouldn't make
a lot of sense to have one.
