Postgresql : pg_temp & pg_toast_temp

[Vishwanath Kummera]

Hello Team
       I am seeing there are many schemas created, this is specially when
enabled "CONCURRENTLY" option for refreshing materialized views through
table trigger.

pg_temp_1... pg_temp_30
pg_toast_temp_1... pg_toast_temp_30

If this is by design the temp schemas get created with the "CONCURRENTLY"
option, is there any way to clean-up them automatically?


Thanks,
Vishu
