Tom Lane	8e8854daa2	Add some basic support for window frame clauses to the window-functions ... patch. This includes the ability to force the frame to cover the whole partition, and the ability to make the frame end exactly on the current row rather than its last ORDER BY peer. Supporting any more of the full SQL frame-clause syntax will require nontrivial hacking on the window aggregate code, so it'll have to wait for 8.5 or beyond.	2008-12-31 00:08:39 +00:00
