  1. postgis: test select from empty table 

    The table has proper ID and GEOM columns, so it must be usable even
though there's no data in it.

  2. postgis: force bbox coordinates to double precision 

    ST_MakeEnvelope accepts coordinates as float8 (double precision).
Use hexfloat format to pass exact values, avoiding wonky conversion
to and from decimal.
