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).
