    I'm  about  99.666667% sure that the lock type choosen in the
    FOR UPDATE case (line  511  of  parse_relation.c)  should  be
    RowExclusiveLock  instead  of  RowShareLock.   Actually I get
    "Deadlock risk" debug messages when selecting FOR UPDATE  and
    then really UPDATE.

    Should I change it?
