It would remove the warning that occurs while applying ALTER ... SET
values. Another case that would change behavior is PGC_S_CLIENT;
I observe that 9.1 rejects bad settings there entirely:
$ PGOPTIONS="--search_path=foo" psql
psql: FATAL: invalid value for parameter "search_path": "foo"
DETAIL: schema "foo" does not exist
but this did not happen in 9.0 so that seems like an improvement too.
I believe that the other possible source values all correspond to cases
where check_search_path would be executed outside a transaction and so
would not do the check in question anyway. I've not tried to prove
that exhaustively though.
