Oh, there is a use-case. If you run your system and then only afterwards realize the I/O from the stats file is high enough to be an issue, and want to change it. That said, I'm not sure the use-case is anywhere near common enough to put a lot of code into it. But I can certainly look at making it a startup GUC. As you say, that'll solve *most* of the cases. //Magnus -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
