[plt-scheme] concurrent database connections

Hi all -

I am wondering what the experiences is in handling concurrent database
connections, say with web-server and SPGSQL.

Do the web-server threads

   - owns its own connection
   - share a single connection
   - share a pool of connections
   - any other approach?

Since postgresql probably cannot support unlimited connections, it seems
having a connection pool might be the proper choice here, but I am wondering
whether people have experiences with any of the approach and can share
thoughts on the subject.

Thanks,
yc
