Take a look at PL/J for postgresql. It runs java as a daemon application server separate from the postgresql backends to process the java procedures while still allowing access to postgresql SPI calls. The procedures are installed into the java app server instead of postgresql directly. I imagine something similar could be created for haskell, but I suspect postgresql's odd type system would pose formidable challenges. http://plj.codehaus.org/ Cheers, M _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
