I found that overly cute also.
It would have been even easier to move StartupCLOG() later, but then we'd need a big comment explaining why CLOG starts up at one point and subtrans starts up at another point, since that is very confusing way of doing things. I wrote it that way first and it definitely looks strange. It's much easier to understand that StartupCLOG() is actually a no-op and that we need to trim the clog at the end of recovery in all cases. The patch isn't meant to be cute, just a better of way of expressing what needs to be done, so I think the patch should stay that way. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
