To make some light on the question:

PostGIS *NEVER* stored geometries in Text format.
Internal representation has always been in binary form.

The difference between 0.x and 1.x is the
*canonical text output representation*

The canonical text output representation is what you get
when fetching a Geometry object from a text cursor. This
is what you get with the 'psql' monitor application, for
example.

Most importantly, canonical text output representation is
the representation used when *dumping* a database. This
is the exact reason why it changed betseen 0.x and 1.x:
to allow lossless dump/restore operations.

I hope this clarify things.
