Terraform vs PostgreSQL RDS

Thanks to new resources (postgresql_default_priviledges) and some fixes Terraform can now add new databases and manage ownership / access to them.

This example creates new database and two users. You can use owner to create new tables and run migrations and user for normal read/write access to database.

# Terraform manifest that creates spot fleet by copying attributed from currently running instance.
# Is has a lot of copy-pasing due to two terraform 0.11 bugs
# - tags with dots in key names forced to copy-paste them in this manifest
# - instance data source does not provide user data script so it had to be manually copied to a file along with this manifest
# both bugs are being worker on in terraform 0.12
