Re: postgres and postgis

OK, but there are datatypes (e.g. POINT etc. in Postgres), and I cannot
access them from PostGIS directly, as PostGIS uses similar geometry
types in a *different* way.

How can I use Postgres geometry datatypes in PostGIS directly? Or do I
have to migrate my data (and, eventually, my old apps too) ?


Is there a possibility to unify the development of these different
datatypes?

Regards,

Hubert
