Log message:
Tom, happier with the attached patch?
I'd have to disagree with regards to the memory leaks not being worth
a mention - any such leak can cause problems when the PostgreSQL
installation is either unattended, long-living andor has very high
connection levels. Half a kilobyte on start-up isn't negligible in
this light.
Regards, Lee.
