Hello
We do not have any temporary tables in the Oracle database. The temporary schema is created only while using the db_link. These temp schemas (pg_temp, pg_toast) are not disappearing even after restarting the database.
These are empty schemas that do not contain anything (tables, views etc). And these schemas keep on increasing each time the query using the db_link is run.
Why the db_link is causing these schemas? Is there any issue with db_link?
Thanks
Regards,
Jill

These schemas contain temporary tables and are not connected to your connection
from Oracle (unless you create temporary tables via that connection).
They are an implementation detail and should not bother you.
What is your problem with these schemmas?
