commit    7bea19d0a9d3e6975418ffe685fb510bd31ab434
Author:   Robert Haas <rhaas@postgresql.org>
Date:     Fri Feb 26 11:03:37 2016 +0000
First released in: 9.6.0

    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.
