  --version           Show version.

PostgreSQL Options:
  -h --pghost=<host>    Postgres hostname. By default uses PGHOST env or "localhost" if not set.
  -P --pgport=<port>    Postgres port. By default uses PGPORT env or "5432" if not set.
  -d --dbname=<db>      Postgres db name. By default uses PGDATABASE env or "openmaptiles" if not set.
  -U --user=<user>      Postgres user. By default uses PGUSER env or "openmaptiles" if not set.

Legacy support, do not use:
  --host=<host>         Obsolete, use --pghost=<...> instead
