Not in all cases.

That section of code has been rewritten many times. I think it is now inaccurate and should be removed. I left it there because the unfortunate history of the project has been the removal of comments and then later rediscovery of the truth, sometimes more than once. I could no longer reproduce that error; someone else may know differently. -- Simon Riggs www.2ndQuadrant.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
