This seems mostly sane, except I think you have not considered the issue of when to clear the smgr_transient flag on an existing SMgrRelation: if it starts getting used for "normal" accesses after having by chance been used for a blind write, we don't want the transient marking to persist. That's why I suggested having smgropen always clear it. Likewise, I think the FD_XACT_TRANSIENT flag on a VFD needs to go away at some point, probably once it's actually been closed at EOXACT, though there's doubtless more than one way to handle that. > This customer is running on 8.4 so I started from there; should I > backpatch this to 8.2, or not at all? I'm not excited about back-patching it... regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
