"create table ao(c int) using ao_row with(parallel_workers=3)" doesn't take effect because only storage options are taken care of in reloptions_gp.c:transformAOStdRdOptions. This PR fixes this by add code processing parallel_workers.

create table ao(c int) using ao_row with(parallel_workers=3)doesn't take effect because only storage options are taken care of inreloptions_gp.c:transformAOStdRdOptions. This PR fixes this by add code processingparallel_workers.The default value of
parallel_workers(-1) is taken fromreloptions.c:intRelOpts. There're no#define-ed constant forparallel_workers's name and default value so I hard-coded them.transformAOStdRdOptionsactually readsWITHclauses before readsStdRdOptions. In the comment they say this is to preserve the order of options because some tests rely on it. I take the value fromStdRdOptionsw/o examiningWITHclause and I see no necessity in doing so. Don't know if this could go wrong :-/Does this PR introduce any user-facing change?
Yes. It fixes a user-perceptible bug.
