conventional env vars

[ReinsBrain]

Just curious why the change in conventional env vars: https://www.postgresql.org/docs/current/libpq-envars.html ... can i still use the postgresql env vars?

The docker-specific variables were chosen so that they wouldn't possibly overlap with those environment variables.

So anything that can be used by the postgres server or client binaries will be used by them. We account for many of them in the startup script (like PGDATA and PGPORT), but it is possible that some could cause the initial database creation steps of the entrypoint script to fail.
