Known problem, I beleive it's even mentioned in the docs.
Basically, if you use temp tables in pl/pgsql, you have to use EXECUTE
for the statements referring to it. The issue is that pl/pgsql is
caching the plan and so tries to use the plan with the old temp table
after the table has gone.
Have a nice day,
