Tom Lane 920c8261d5 Improve the error message given for modifying a window with frame clause. ... For rather inscrutable reasons, SQL:2008 disallows copying-and-modifying a window definition that has any explicit framing clause. The error message we gave for this only made sense if the referencing window definition itself contains an explicit framing clause, which it might well not. Moreover, in the context of an OVER clause it's not exactly obvious that "OVER (windowname)" implies copy-and-modify while "OVER windowname" does not. This has led to multiple complaints, eg bug #5199 from Iliya Krapchatov. Change to a hopefully more intelligible error message, and in the case where we have just "OVER (windowname)", add a HINT suggesting that omitting the parentheses will fix it. Also improve the related documentation. Back-patch to all supported branches.		12 years ago
