Обсуждение: Temp tables, question

I have a question, temporary tables are killing me,
1. Live in session scope, but does not care about function scope
   so temp table created once in a function will be visible during
second function
   execution (same session), of cause I can drop it manually, but ....
   any changes of that in 7.4?

2. PGPLSQL cache temp tables somehow, so when I drop table and call
function again,
   that will say 'relation xxxxxxxx cache lookup failed' or something,
   that basically renders usage of temp tables useless, or you have to
drop connection
   every time ( what I am doing now ) ( slow no connection pooling ) or
do not use
   temp table or run dynamic SQL that is in most cases ugly or even
unusable.
   any changes in 7.4?

Thank you
