aliases for temp tables....
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 :-)

AFAIK there is no way to retrieve the temp-table name mapping from the
backend. Sorry ...
When we implement schemas (hopefully for 7.2) perhaps it will be
possible to reimplement temp tables in a slightly less klugy way,
so that this sort of problem goes away.

There is a linked list stored in utils/cache/temprel.c. There is no
interface to that linked list.
