#5732: Error on Doc Page for ST_Touches
---------------------------+---------------------------
 Reporter:  tunasplam      |      Owner:  robe
     Type:  defect         |     Status:  new
 Priority:  low            |  Milestone:  PostGIS 3.4.3
Component:  documentation  |    Version:  3.4.x
 Keywords:                 |
---------------------------+---------------------------
 The mathematical definition for ST_Touches appears to have a mistake. The
 first clause reads $Int(A) \cap Int(B) \neq \emptyset$ but, because the
 interiors of polygon's A and B should not intersect, it should instead be
 equal to the empty set.
