Not sure how fast is “fast” for your system. You could try:
create database customer_test with template customer;
I’m able to duplicate a 20GB in a couple minutes with the above command.
Couple caveats:
1. No active connections to customer are allowed during the create.
2. You’ll likely have to recreate the search_path and reissue connect grants to the newly created database.
