Is there a way to access temporary tables of other sessions in postgres? I'm working with a Windows application that uses a (local) postgres Database and stores some information in a temporary table. I'd like to have a look at the temporary table, but pgadmin and dbVis tell me: ERROR: cannot access temporary tables of other sessions when trying to query the data. I tried changing the permissions of the schema and table, but this didn't seem to help, even though I'm accessing the database with the same user as the program itself (at least in dbVis). Is there a setting I can change in my database that allows me to have "root" access to all session in my database?
The lack of access to temporary tables in other sessions is not a matter of permissions, it's a technical limitation of the design. A PostgreSQL backend can't access temporary tables of another backend because none of the usual housekeeping to allow concurrent access is done for temporary tables.

In 9.2 you will want to use an UNLOGGED table instead; this can be visible from other sessions, but retains most of the performance benefits of a temporary table.
