Not without doing a truly vast amount of infrastructure work first. Infrastructure work that, by and large, would add cycles and lose performance. So by the time you got to the point of being able to do micro-optimizations like parallelizing individual functions, you'd have dug a pretty large performance hole that you'd have to climb out of before showing any net benefit for all this work. If you search the PG archives for discussions of threading you should find lots and lots of prior material. regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
