Autobase create database

[algoritmsystems]

1. I created a database via ansible, and changed some parameters.
   Updating the config ansible-playbook config_pgcluster.yml , will recreate the new database, i.e. will it erase the data?

postgresql_databases: []
  - { db: "mydatabase", encoding: "UTF8", lc_collate: "ru_RU.UTF-8", lc_ctype: "ru_RU.UTF-8", owner: "mydb-user" }
  - { db: "mydatabase2", encoding: "UTF8", lc_collate: "ru_RU.UTF-8", lc_ctype: "ru_RU.UTF-8", owner: "mydb-user2" }

2. and is it possible to configure separate pgbouncer processes for each database separately?
   pgbouncer_pools:

  - { name: "postgres", dbname: "postgres", pool_parameters: "" }
  - { name: "mydatabase", dbname: "mydatabase", pool_parameters: "pool_size=20 pool_mode=transaction" }
  - { name: "mydatabase2", dbname: "mydatabase2", pool_parameters: "pool_size=100 pool_mode=transaction" }

How to configure such parameters default_pool_size = 100, reserve_pool_size = 30, max_db_connections = 150, max_client_conn = 3000, query_wait_timeout = 90 ... in such case?
- { name: "mydatabase2", dbname: "mydatabase2", pool_parameters: "default_pool_size = 100, reserve_pool_size = 30, max_db_connections = 150, max_client_conn = 3000, query_wait_timeout = 90 pool_mode=transaction" } so?
Thanks!

1. A new database will be created, if it does not exist, the data will NOT be deleted.
2. Yes, you can set some parameters separately at the pool level, but only those that support pgbouncer, the rest must be defined globally.

which parameters belongs to the pool level?
Are this parameters belongs:
default_pool_size =
reserve_pool_size =
max_db_connections =
max_client_conn =
query_wait_timeout =
pool_mode=
