pgsql: Add a WINDOW attribute to CREATE FUNCTION, and teach pg_dump

Log Message: ----------- Add a WINDOW attribute to CREATE FUNCTION, and teach pg_dump about it, so that user-defined window functions are possible. For the moment you'll have to write them in C, for lack of any interface to the WindowObject API in the available PLs, but it's better than no support at all. There was some debate about the best syntax for this. I ended up choosing the "it's an attribute" position --- the other approach will inevitably be more work, and the likely market for user-defined window functions is probably too small to justify it.
