In terms of runtime I strongly suspect the effect would be 0 due to branch prediction. The effect on the code cleanliness seems like a stronger argument but I have a hard time getting upset about a single one-line if statement in namestrcpy. I suspect the argument may have been that we have no reason to believe namestrcpy is the only place this can happen. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
