"""
This is a simple vector tile server that returns a PBF tile for  /tiles/{z}/{x}/{y}.pbf  requests

Usage:
  postserve <tileset> [--serve=<url>] [--port=<port>] [--key] [--gzip [<gzlevel>]]
                      [--no-feature-ids] [--file=<sql-file>]
                      [--layer=<layer>]... [--exclude-layers]
                      [--pghost=<host>] [--pgport=<port>] [--dbname=<db>]
                      [--user=<user>] [--password=<password>]
                      [--test-geometry] [--verbose]
  postserve --help
  postserve --version

  <tileset>             Tileset definition yaml file

Options:
  -l --layer=<layer>    If set, limit tile generation to just this layer (could be multiple)
  -x --exclude-layers   If set, uses all layers except the ones listed with -l (-l is required)
  -s --serve=<url>      Return this URL as tileserver URL in metadata  [default: http://localhost:<port>]
  -p --port=<port>      Serve on this port  [default: 8090]
  --key                 If set, print md5 of the data to console (generated by Postgres)
  --gzip                If set, compress MVT with gzip, with optional level=0..9.
  --no-feature-ids      Disable feature ID generation, e.g. from osm_id.
                        Feature IDS are automatically disabled with PostGIS before v3
  -g --test-geometry    Validate all geometries produced by ST_AsMvtGeom(), and warn.
  -v --verbose          Print additional debugging information
  --help                Show this screen.
  --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.
  --password=<password> Postgres password. By default uses PGPASSWORD env or "openmaptiles" if not set.
  --file=<sql-file>     Override SQL file generated by generate-sqltomvt script with the --query flag

These legacy environment variables should not be used, but they are still supported:
  POSTGRES_HOST, POSTGRES_PORT, POSTGRES_DB, POSTGRES_USER, POSTGRES_PASSWORD
