On second thought, disable parallelism for prepared statements.
CREATE TABLE .. AS EXECUTE can turn an apparently read-only query into
a write operation, which parallel query can't handle. It's a bit of a
shame that requires us to avoid parallel query for queries prepared via
PREPARE in all cases, but for right now it does.
