Yandex cloud Managed PostgreSQL terraform module

Usage

This module creates databases and users with nessecary permissions. Some important things before usage:

  1. configure maintenance_window
  2. specify the encoding - after creation DB there is no possibility to change it
  3. specify resource PostgreSQL cluster: instance type by cpu, type and size of disk
  4. for create HA instance specify multiple "hosts" block
  5. read the full doc of yandex: https://registry.terraform.io/providers/yandex-cloud/yandex/latest/docs/resources/mdb_postgresql_cluster
