I've been looking everywhere and I can't find this: Everytime I create a temp table (Thanx Tom) within a procedure, a table named like pg_temp.###.# is created (I know this is MY temp table). How can I know the name (or alias) for this table so that I can, later on, check if it already exists. Example: I use a function to create a temp table named "mitabla1", so a physical table named pg_temp.32326.0 is created. I also create a temp table named "mitabla2" -> pg_temp.8732.2. I know there has to be a way of knowing which is which becuase if I run a select over "mitabla" I get the contents from the corresponding pg_temp.... table. I just couldn't find anywhere this information. Can anybody tell me where to find it or how? Thanx P.S. If I wasn't clear enough please let me know..... Cheers :-)
