Create artificial size and load on staging

The idea here will be creating some tables with a few TB, to simulate a bit more production in our exercises in staging. Also, we are not impacting the existing tables in the staging database.

The goal will be have 3 TB of fake data.

Also generate some load on that by some pipeline/script

e.g.:

2000 reads / sec

1000 inserts / sec

500 updates / sec

1000 deletes / sec

My intention is to bring some activity to the staging, and size, that in some scenarios we see different scenarios based on wal activity and size, etc.
