[postgis-users] Does ST_AsText truncate or round

[Paul Ramsey]

Kevin might have some thoughts, he's wrestled with this.

You could put a post-update, post-insert trigger that runs a fine snap
to grid. This will ensure that all vertices remain cojoint. What it
won't do is help with places of co-linearity where there are not
co-vertexes.
