What's the actual use case for this feature other than it would be good to have it? A log message is here to give information about the state of something that happens in backend, but in the case of this function the event that happens is the content of the function itself. It also adds a new log level for something that has a unique usage, which looks like an overkill to me. Btw, you could do something more advanced with simply an extension if you really want to play with this area... But I am dubious about what kind of applications would use that. -- Michael -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
