PostGIS layer

[brunj7]

Hi,

First thanks for this awesome module. Second, I have a question regarding the implementation of PostGIS tables. When I try to replace what I was doing using shapefile with postGIS queries, I get an error message stating the SRIDs are not matching:

cur.execute('SELECT "%s" FROM %s WHERE %s' % ('", "'.join(fields), self.table, query))
psycopg2.InternalError: Operation on mixed SRID geometries

I am only using the US States table with SRID 4326 for this test. Here is my config:
"layers": {
"slayer":{"src": "postgis:dbname=postgres user= postgres password= host=localhost",
"table": "states",
"attributes": {
"id": "stusps"}
}
},

Do I need to set the projection or add a bbox when using postgis?

Thanks,

Julien
