Are there strategies for dealing with TopologyException errors in PostGIS 2? Nearly every function I run against two geometries results in a TopologyException (e.g. ST_Intersection, ST_SymDifference).
I always try ST_Buffer(the_geom, 0) first, then ST_MakeValid(), then (ST_Dump(the_geom).geom and repeat ST_Buffer. Sometimes a combination of one or more fixes it, sometimes not.
Perhaps my data is just not clean enough for PostGIS 2? I feel like I rarely had this issue on Postgres 9.0 with PostGIS 1.5, but now it is almost every dataset.
