I wonder whether the current versions of postgres (i.e. either 8.2 or 8.3) are able to utilize multiple cores for the execution of a single query?

This is one thing that systems like SQL Server and Oracle have been able todo for quite some time. I haven't seen much in the documentation that hints that this may be possible in PG, nor did I find much in the mailinglists about this. The only thing I found was a topic that discussed some patches that may eventually lead to a sequence scan being handled by multiple cores..

Could someone shed some light on the current or future abilities of PG for making use of multiple cores to execute a single query?

Thanks in advance
