> When you execute a wrong SQL command after create a TEMP TABLE,
postgres backend doesn't drop this table after connection ends. We can't
drop pg_temp.PID.N with "drop table" command because it is a system
catalog table. So, we had to dumpall the database, edit db.out file to
erase lines of pg_temp??? create table and reload it again.

I can confirm that this a bug. I am looking at it now. As a
workaround, you can delete the temp tables by starting a postgres
backend with the -O flag to allow system table modifications, and
droping the table.
