Yes, I realized it after some thought - adding nonstandard syntax isn't
so great after all. Right now I'm wondering if SQL standard window
functions can do the things I though could be doable with preferences.
Maybe I should talk to my thesis supervisor and find out if implementing
window functions would be an equally good subject...
I suppose having window functions would be a nice thing? To be honest -
I need a thesis subject and I like fiddling with Postgres. I'm trying to
find an area in which my work would be useful to the community and
enough of a standalone feature, that I can use it as the basis of my
dissertation.
Also, going through the PG development process will ensure that the
resulting code will be of topmost quality ;)
