Well, the trouble is that we have these pesky SECTION_NONE entries for
things like comments, security labels and ACLs that need to be dumped in
the right section, so we can't totally ignore the order. But we could
(and probably should) ignore the order for making decisions about
everything BUT those entries.
So, here's a revised plan:
--section=data will dump exactly TABLE DATA, SEQUENCE SET or BLOBS
entries --section=pre-data will dump SECTION_PRE_DATA items (other than
SEQUENCE SET) plus any immediately following SECTION_NONE items. --section=post-data will dump everything else.
Comments?
cheers
