Avoid core dump for empty prepared statement in an aborted transaction.
Brown-paper-bag bug in commitab1f0c8: the old code here coped withnull CachedPlanSource.raw_parse_tree, the new code not so much.Per report from Dave Cramer.No regression test, because our core testing infrastructure doesn'tprovide any easy way to exercise this path. Fortunately, the JDBCcrew test it regularly.Discussion:https://postgr.es/m/CADK3HH+Ug3xCysKqw_dZOnaNnytZ1Rh5yP05hjO-e4NoyRxVvA@mail.gmail.com
