#4182: Unexpected TopologyException during ST_Union aggregate function with valid

Comment (by blaggner):
That is interesting to know! Even though the tiny holes will surely be
unwanted for further processing, I immediately have ideas how to possibly
deal with them as long as the ST_Union is able to run without an error.
But, weren't there improvements in planning that would enable ST_Union and
other functions to run with a user-defined reduced accuracy? That would
surely solve (or reduce) the sliver problems, don't you think?
