Hello!

I've some questions around Backup & Restore.

1: Is it necessary to perform a VACUUM and REINDEXING operation after restoring the dump from Postgres 9.6 to Postgres 13? The dump size could be 1/2 TB to 1 TB.

2: Also, are there any other operations that are recommended to perform after pg_restore? 

3: What is the minimum required disk space if taking a dump on the same machine where the source database exists? Is it the "size of the current data folder x 2"?

Thanks.
Hasan
