Maybe so, but the parser is expected to put out a representation that
will still be valid when the command is executed some time later.
That is exactly why utility statements have the barely-more-than-source
parsetree representation they do: because we do not hold locks on the
objects from parsing to execution, we could not expect an OID-level
representation to remain good. This is a lot different from what we
do with DML statements, but there are good reasons for it.
I repeat my observation that this code doesn't belong in /parser.
The code you're replacing was not in /parser, and that was because
it didn't belong there, not because somebody didn't understand the
system structure.
