It is in the same part of the code, but seems directed at a different
goal (which I disapproved of, IIRC). But we definitely need the
principle that any type OID appearing in an expression tree needs to
be logged, except in cases where there's necessarily an indirect
dependency (eg, a function or operator's result type doesn't need to
be logged separately).
