This is true to a point. Since my DB is dormant from 11 PM PST time
until 5 AM PST time, I'm not concerned about the table relationships
getting out of sync. I guess this isn't the most eloquent way of
doing this, but it works for me...

So based upon your comment, pg_dump locks the database while running,
preventing any data inconsistencies?

transaction, meaning it does not make a consistent backup. I
recommend
pg_dump in -Fc mode and the use of pg_restore.
