Did you try ST_SnapToGrid() to force your geometries to lie on a grid?

Note: this is close to, but not the same thing as, reducing the precision on
geometry coordinates.

Hi there,
I have two feature classes which are supposed to have shared boundaries.
However, the data came from another party with the shared boundary data
issue, which boundary lines are slightly moved (no snapping during
editing?). I am thinking how I can solve the data problem by using
PostGIS methods.
Any input would be greatly appreciated!
Thanks a lot
John
