Additionally, they introduce environment variables to enforce MD5 host authentication for PostgreSQL containers, ensuring consistent authentication behavior during initialization.

Changes

File(s)	Change Summary
Tests/AppTests/Helpers/ShellOutCommand+ext.swift	Updated Docker image from postgres:13-alpine to postgres:16-alpine and added MD5 auth env vars.

Poem

A hop to sixteen, our Postgres grows,
With MD5 auth, security flows.
In scripts and helpers, changes align,
Containers now run just fine.
The rabbit leaps with Docker cheer,
New versions, fresh carrots, and code sincere! 🐇🥕

❓ Verification inconclusive

PostgreSQL version upgrade from 13 to 16

This is a major version upgrade from PostgreSQL 13 to 16. The upgrade aligns with the PR objective to switch to PG 16.

Consider running the following to check for any new container startup parameters or configuration options that might be beneficial to include with PostgreSQL 16:

🏁 Script executed:

docker run --rm postgres:16-alpine postgres --help

Manual verification required for PostgreSQL 16 startup parameters

The sandbox environment couldn’t run docker, so please execute the following locally to check for any new options introduced in PostgreSQL 16:

• File: scripts/start-ci-dbs.sh
  Lines: 21

docker run --rm postgres:16-alpine postgres --help

25-26: Authentication method explicitly configured to MD5

Good implementation of MD5 authentication method to match the changes in the CI script. Note that the format for POSTGRES_INITDB_ARGS is slightly different here (no quotes) compared to the shell script, but both formats are valid.

31-31: PostgreSQL version upgrade from 13 to 16

Upgrade to PostgreSQL 16 matches the change made in the CI script, ensuring consistency across test environments.
