Feature request: REPLICATION_PASSWORD_FILE

[HernanMora]

First of all, excellent work!

PostgreSQL allows you to configure passwords using the Docker secrets. For example: POSTGRES_PASSWORD_FILE.

Can the same thing be done with REPLICATION_PASSWORD?

Regards!

Sorry,

To be more clear, the following environment variables should be added:

postgresql

• REPLICATION_PASSWORD_FILE

barman

• REPLICATION_PASSWORD_FILE
• POSTGRES_PASSWORD_FILE

pgpool

• CHECK_PASSWORD_FILE
• PCP_PASSWORD_FILE

Regards!

It would also make sense to then add REPLICATION_USER_FILE, POSTGRES_USER_FILE and PCP_USER_FILE, as one might want to move those to secrets as well.
