[postgis-devel] Path from constrained to typmod'ed definitions

With my dump/restore tests I end up with half tables
using constraints and half tables using typmod.
Example:
sqlmm_topology.edge_data.geom is of type geometry and has:
"enforce_dims_geom" CHECK (st_ndims(geom) = 2)
"enforce_geotype_geom" CHECK (geometrytype(geom) = 'LINESTRING'::text
OR geom IS NULL)
"enforce_srid_geom" CHECK (st_srid(geom) = 0)
small_sample_topo.edge_data.geom is of type geometry(LineString)
and has no constraints
I wouldn't try to mess with those definitions at restore time, to reduce
the risk of broken restores, but I would probaby want to convert all
structures to the new format, dropping the constraints and converting
to typmod. Is there any such function or script already ?
