Upgrade the replica db

[dadiorchen]

DONT MERGE THIS

After upgraded the replica read-only node for the DB, there are some problems in the terraform:

1. The treetracker-postgres-read-replica has been, but the CLI failures with error shown below, but actually the readonly node has been created correctly (shows up in the panel), and if we execute plan/apply again, the terrforma will still try to create it but throws error when applying
2. The two db: world_bank_backup, ckan_storage is already in the DB, but terrforma is trying to create it, but will fails when applying
