#4788: ST_SquareGrid (and others) don't support points on input
-------------------------+---------------------------
 Reporter:  tobwen       |      Owner:  pramsey
     Type:  enhancement  |     Status:  new
 Priority:  medium       |  Milestone:  PostGIS 3.1.0
Component:  postgis      |    Version:  3.0.x
 Keywords:               |
-------------------------+---------------------------
 == current situation
 Currently, ''ST_SquareGrid'' (and similar functions) only supports
 polygons as input. When using points, there's neither any output nor a
 warning.

 == suggestion
 In many cases, it's useful to generate a grid, which is based on a point.

 == current workaround
 Buffer the point a little bit.
 {{{
  SELECT * FROM ST_SquareGrid(1E1, ST_Buffer(ST_SetSRID(ST_MakePoint(12345,
 54321), 3857), 1E-11));
 }}}
