vacuumdb: permission denied for schema "pg_temp_7"

Repo steps

1. Create a temporary table

sample => CREATE TEMPORARY TABLE temp_employees (
> id SERIAL PRIMARY KEY,
> name VARCHAR(100),
> position VARCHAR(50),
> salary NUMERIC(10, 2)
> );
> CREATE TABLE
> sample => \dt pg_temp_*.*
> List of relations
> Schema | Name | Type | Owner
> -----------+----------------+-------+----------
> pg_temp_7 | temp_employees | table | vaibhave
> (1 row)

2. Run vacuumdb

vacuumdb: vacuuming database "sample"
> vacuumdb: error: processing of database " sample " failed: ERROR:
> permission denied for schema pg_temp_7

Temporary tables can only be accessed within the session which created
them. They should be skipped during vacuumdb.
