Hi,

We have the need to be able to execute entrypoints on each start.
As of now the only entypoint available is executed on first start with initdb: docker-entrypoint-initdb.d

To work around this, we modify your alpine image to add another entrypoint docker-entrypoint-init.d in docker-entrypoint.sh this way:

...
_main() {
	...
	if [ "$1" = 'postgres' ] && ! _pg_want_help "$@"; then
		...
		# only run initialization on an empty data directory
		if [ -z "$DATABASE_ALREADY_EXISTS" ]; then
			...
			docker_process_init_files /docker-entrypoint-initdb.d/*
			...
		else
			...
		fi
		echo "Process custom init file "
		docker_process_init_files /docker-entrypoint-init.d/*
		echo "Process custom init file done "
	fi

	exec "$@"
}
...

Can you add such an entrypoint to the image ?
This will allow to restore db from volumes on start, make additional configurations...
