#3976: Mark ST_Transform as STABLE
---------------------+---------------------------
 Reporter:  pramsey  |      Owner:  pramsey
     Type:  defect   |     Status:  assigned
 Priority:  high     |  Milestone:  PostGIS 2.5.0
Component:  postgis  |    Version:  trunk
 Keywords:           |
---------------------+---------------------------
 As @robe noted in #3952, ST_Transform is marked IMMUTABLE, and that it
 clearly is not, since the underlying spatial_ref_sys table can change at
 any time. I think "STABLE" is a better description of how it is
 operationally (safe to cache results in most operational contexts,
 certainly within a transactional one).
