Changes (by robe):

 * milestone:  PostGIS 3.0.10 => PostGIS 3.5.0

Comment:

 I think we probably need to drop some of these definitions, but given no
 one else has complained, I suspect they aren't widely used.  Presumably
 cause they aren't documented so no one knows about them.

 I recall Bborie having created these to get speedier but less accurate
 calculations.

 At anyrate the fix sounds like to drop overlapping sql signatures which
 qualifies as an api change, so we can't do this until 3.5.0 per our rules.
