func NewProvider ¶

func NewProvider(config map[string]interface{}) (mvt.Provider, error)

NewProvider Setups and returns a new postgis provide or an error; if something is wrong. The function will validate that the config object looks good before trying to create a driver. This means that the Provider expects the following fields to exists in the provided map[string]interface{} map. host string — the host to connect to. port uint16 — the port to connect on. database string — the database name user string — the user name password string — the Password max_connections *uint8 // Default is 5 if nil, 0 means no max. layers map[string]struct{ — This is map of layers keyed by the layer name.

   tablename string || sql string — This is the sql to use or the tablename to use with the default query.
   fields []string — This is a list, if this is nil or empty we will get all fields.
   geometry_fieldname string — This is the field name of the geometry, if it's an empty string or nil, it will defaults to 'geom'.
   id_fieldname string — This is the field name for the id property, if it's an empty string or nil, it will defaults to 'gid'.
