I would definitely like to see it.

The only thing about GSL is that it would make it easier to tie into
some very sophisticated stuff later, and (I think) the basic linear
algebra is probably just as fast as CBLAS, and we could implement it
first. It would also be easy to define a big project as : "bring GSL
to Postgres", and then people could work on pieces. But if you
actually write it, you get to decide :)
GSL licensing is GNU ish, so may be that is a deal breaker, too.
