Maybe you can use dblink to retrieve the results from the various
"parallel servers" into one central server and then merge them (UNION,
maybe?). That would work for simple SELECTs, but when you have a couple
of triggers you start getting into trouble.
Obviously you would have to split UPDATEs and INSERTs appropiately.
Who knows, maybe you can even get it to actually work.
