Temp tables

Hi,

To enhance the performance of the queries, I use temp tables in my website
reports.

It seems that a temp table has not been dropped automatically in a certain
session, and now the report is giving an error since the temp table already
exists ?!

When I type the following, the database gives me an error:

dragon=# CREATE TEMP TABLE _parcours (id int);

ERROR: type "_parcours" already exists

1. How can I identify the session in which the temp table is still
locked, so I can drop it manually

2. Why does those cases happen and the temp tables don’t drop
automatically

I’d appreciate a quick reply

Thanks in advance
