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.
Postgres will keep empty pg_temp schemas around rather then having to
recreate them the next time they are needed. Not sure where the cutoff
is for number?
Why the db_link is causing these schemas? Is there any issue with db_link?
Thanks

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?
