Just a thought:
Wouldn't it be sufficient to have the "temporary", fast session-table
in a RAM-disk? I suspect you could do this rather easily using a TABLESPACE.
All the indices could be in this TABLESPACE as well (at least after
having a quick look at the short help for CREATE TABLE and assuming you are
using PostgreSQL >= 8.0).
