No way to run postgres in a container with additional options.

[Wolvverine]

For example -m smart to repair the database.

	# if first arg looks like a flag, assume we want to run postgres server
	if [ "${1:0:1}" = '-' ]; then
		set -- postgres "$@"
	fi

It should process flags, could you give all the commands you ran and the docker logs?

I'm not sure which utility would have the -m option but I don't see it in Postgres' repertoire

# postgres --help | grep -i "\-m"
  -S WORK-MEM        set amount of memory for sorts (in kB)

postgres --help

$ docker run -it --rm postgres bash
root@a2aa0d74b979:/# postgres --help
