The function exists within GEOS, which is a library used by PostGIS.
But the specific functionality (snapping) isn't exposed in SQL yet.
What you could do is implement or fund implementation of
the missing bit (the wrapper).
I've always found snapping a very important function in all kinds of
(carto)graphic environments. Could you give an indication how much time
it would cost to write the PostGIS wrappers? If the algorithm already
exists in GEOS, exposing it in PostGIS doesn't look like a major problem
to me.
