 Priority:  high     |  Milestone:  PostGIS 2.4.1
Component:  postgis  |    Version:  2.4.x
 Keywords:           |
---------------------+---------------------------
 This warning is showing up in our stable branch, which gives me the
 willies. Can we have the clean solution ported back from trunk please?
