Read default postgres compose service name and default django compose
service name from env variables.
AHAB_POSTGRES_CONTAINER - defaults to `appserver`
AHAB_DJANGO_CONATINER - defaults to `postgresdb`
Default values are there for 100% backwards compatibility.
Unified expected output to always eprintln so outputs can be piped to
other processes. Added debug_eprintln and switched all occurances of
debug_println.
Fixed bug where restore commands were called inside pg_isready loop.
Made CommandBuilder::build public. Redirected stdout for pg_isready
calls to /dev/null via Stdio::null().
Fixed issue where arguments passed to `compose stop` weren't passed to
the underlying command. Added pg_isready call between each command call
in restore script.
Implemented custom command builder with nicer api suited for my needs.
Also returned error if there are no containers in
`scripts::postgres::get_containers`.
Implemented basic wanted functionality for postgres subcommands. We
currently assume that postgres is running in docker-compose project in a
service named "postgresdb". This could be looked at and changed at some
point in the future.
Made initial command scopes
d -> docker related commands
dc -> docker compose related commands
dj -> django related commands
pg -> postgres related commands
