Hmmm. I don't understand how that currently works then. Because I've been
able to create and use temporary tables. Since temp tables are
one-session-only, how is it currently working?

A number of reasons:
1) Our data-load routine requires us to turn of replication and do binary sync
every night.
2) Slony doesn't handle temp tables, either.
3) One of the things we need to replicate during the day are temporary "load
tables" holding raw data. These tables have no primary keys, and adding
primary keys (due to the constraint) significantly increases load time.
4) Our data loads are often in the order of 3 million records at a go. Slony
performs poorly with such large bulk loads.
