Notes

Automatic population of database

PostgreSQL supports creating databases based on templates. (See CREATE DATABASE) This functionality can be used to effectively pre-populate a database as it is provisioned.
It is important to be familiar with the constraints of template databases in PostgreSQL. The documentation states:
Although it is possible to copy a database other than template1 by specifying its name as the template, this is not (yet) intended as a general-purpose "COPY DATABASE" facility. The principal limitation is that no other sessions can be connected to the template database while it is being copied. CREATE DATABASE will fail if any other connection exists when it starts; otherwise, new connections to the template database are locked out until CREATE DATABASE completes.
For more information on managing template DBs, see https://www.postgresql.org/docs/current/manage-ag-templatedbs.html

Example

To create a fresh PostgreSQL database in an instance available at dev-postgres.example.com:
curl https://api.humanitec.io/orgs/${HUMANITEC_ORG}/resources/defs \
-X POST \
-H "Authorization: Bearer ${HUMANITEC_TOKEN}" \
-H "Content-Type: application/json" \
--data-binary '
