All true, but it works well enough today that it serves an often needed role. And it is plenty fast, at least for use cases for which I've needed it. > I'd rather see us invent a real session-variable mechanism instead > of putting yet more demands on GUC that have nothing to do with its > primary mission, and indeed are antithetical to it. Also true, but since no such effort exists today that I'm aware of, there is little chance we will have that real mechanism any time in the next 24 months at the least, because I doubt even the bikeshedding could be finished before we lock down 9.6 :-( Joe -- Crunchy Data - http://crunchydata.com PostgreSQL Support for Secure Enterprises Consulting, Training, & Open Source Development
