There are a number of things that need to be moved from initdb to be settable parameters, so this is just one of them, for later releases. We should be able to enforce one setting of the parameter at bootstrap time, so the system indexes all get built the standard way with the initdb locale. We can then be free to set the locale for indexes after that, but that is another issue. > I put this in the same category as altering the identifier case-folding > rules.

I don't suggest we should be _all_ things to _all_ people, just that we should try to be provide our capabilities to _more_ people. I think its a great feature and I want to see more people appreciate that. -- Simon Riggs 2ndQuadrant http://www.2ndQuadrant.com ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
