Comment (by jdsterritt):

 Setting the cost on ST_Centroid to 1.0 corrects the index usage. I've have
 verified this in both the query plan and in our test environment.

 Setting the cost on ST_SnapToGrid to 1.0 doesn't help and it appears the
 indexes are missed. This was verified in both the query plan and test
 environments.
