As far as I can tell, the PG storage manager API is at the wrong level of abstraction for pretty much everything. These days, everything we do is atop the Unix filesystem API, and anything that smgr might have been able to do for us is getting handled in kernel filesystem code or device drivers. (Back in the eighties, when it was more plausible for PG to do direct device access, maybe smgr was good for something; but no more.) It's interesting to speculate about where we could draw an abstraction boundary that would be more useful. I don't think the MySQL guys got it right either... 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
