Do you think we could make it a view ? I've made some research some
time ago on this.
If we make use of custom DOMAINs we could detect geometry type and nDims
and also stick type-constraint to the domain instead of the table
(OGCPolygon2d, OGCPolygon3D, etc)
What remains is the SRID value, which still needs to be written somewhere
custom_datatype(custom_parameter) support has been discussed
on pgsql-hackers, but I do not know if something moved on since then.
That syntax would allow to specify a SRID which would be put in
the pg_attribute table for public use.
News from that front Mark ?
