Hi Joe,
I don't know if the speed will meet your needs, but you might test
to see if PL/R will work for you:

You could use pg.spi.exec() from within the R procedure to grab the
arrays, do all of your processing inside R (which uses whatever BLAS
you've set it up to use), and then return the result out to Postgres.
Thanks a lot for the hint, I'll give it a try. It also will be much
easier to implement a prototype :-)
Bye,
e.

match
