Tom, happier with the attached patch?
I'd have to disagree with regards to the memory leaks not being wortha mention - any such leak can cause problems when the PostgreSQLinstallation is either unattended, long-living andor has very highconnection levels. Half a kilobyte on start-up isn't negligible inthis light.Regards, Lee.Tom Lane writes: > Lee Kindness <lkindness@csl.co.uk> writes: > > Guys, attached is a patch to fix two memory leaks on start-up. > > I do not like the changes to miscinit.c.
