I see that initdbArgs is already an option under postgres.nix only thing that I have to add is an option to specify POSTGRES_HOST_AUTH_METHOD, right?

[srid]

I'd think so, yes.

But, IIRC using initdbArgs in passetto didn't work for some reason (which is why it is commented out).

Ultimately, we want to make sure that the passetto PR works after this change (whatever that is).

[shivaraj-bh]

As per discussion with @srid over a call. The following is the checklist to verify if the change made to resolve the issue works:

• nix run on github:/nammayatri/passetto/nixify should start all the services on darwin (atm only works on linux)
• Configure user authentication methods (pg_hba.conf) in services-flake.

[shivaraj-bh]

This PR will allow you to manage user authentication methods by letting you configure pg_hba.conf file in Nix. Allowing us to get rid of POSTGRES_INITDB_ARGS = "--auth=scram-sha-256" and POSTGRES_HOST_AUTH_METHOD = "scram-sha-256".

Check here to see this in action on passetto repo.
