[postgis-users] Error: different SRIDS

["R. Müller"]

Hallo Josh,

you can also use the GEOMFROMTEXT-function to get a geometry from your
polygon. There you have to explicitly pass a SRID as second argument.

The other polygon you mentioned, is the geometry-implementation
postgresql. But that won't work with postgis.
