Here is a patch that allows people to delete the pg_temp* tables used as
temp tables. They are left around after a backend crash and the only
way previously to remove them was to start postgres with the -O override
option.
I am wondering if pg_temp tables should even be seen as system tables by
IsSystemRelationName(). We have to call them pg_ so user applications
don't display them, but other than that they aren't like system tables.
Comments?
There are no tests to see if the table is actually in use. I can add
them if people want it.
---------------------------------------------------------------------------
test=> CREATE TEMP TABLE test (x int);
CREATE
test=> \dS
