Hi:
How user specific is pg_tables when it comes to temporary tables? It seems to pick up the existence of a a temp table created by the same user but a different session. Here’s the demo scenario....
Session 1:
mydb=# create temporary table foo (a int);
Session 2:
stdb2=# select tablename from pg_tables where tablename = 'foo';
tablename
-----------
foo
(1 row)
Session 1:
stdb=# drop table foo;
Session 2:
stdb2=# select tablename from pg_tables where tablename = 'foo';
tablename
-----------
(0 rows)
mydb=# insert into foo (a) values (3);
ERROR: relation "foo" does not exist
So Session 2 is detecting foo, but it doesn’t own it.
I can live with this as long as there’s a way that I can determine if the table it found does not belong to the current session. Is there a more elegant way of doing this other than trying to do something with the table (select, insert, delete...) and trapping a failed attempt? The contents of pg_tables appears to be the same from both the owning and non-owning sessions.
Thanks in Advance for any help.
