[postgis-devel] Minimum number of points in a POLYGON ring?

[Chris Hodgson]

What if the two modes of operation were "reject invalid geometries" and 
"automatically fix invalid geometries (in ways which are clearly 
documented)"? This way we get to assume a standard level of data quality 
that is slightly above "unknown", and (if we set rejection as the 
default) we make sure that the user knows that we are fixing their data 
for them. Also, this seems like it should introduce less of a second 
path through the code, only a single "if it's broke, fix it" should be 
required.

Or perhaps the ideal system has all three options, including these two 
and the "we'll take whatever you got" option. But then we don't get the 
nice assumption of a minimum quality level.
