I have a strange problem.Document says that one can create a temporary table in a session. I had created a temporary table in languge plpgsql.(Actually in a procedure). After completing my task I droped a table within a seesion(In same Function). Now problem arises. When I again calles that stored procedure (Function) then it says relation does not exist . What may be the cause of that problem. It is urgent. I need ed thi function as internal function so it called again and again.
I had attached Code as well as error.
I am Using RedHat 7.1,Postgresql 7.1.2
Thanks
