Since version 1.1.0 asText() doesn't return the SRID anymore.

The 'SRID=#;' prefix to WKT is a postgis extension, thus
only returned by asEWKT() and no more by asText(), which
is an OGC defined method.

Alternatively, the OGC standard SRID(geometry) function
will be available on all PostGIS versions.
