 Reporter:  Robins       |      Owner:  pramsey
     Type:  defect       |     Status:  new
 Priority:  medium       |  Milestone:  PostGIS 3.1.2
Component:  postgis      |    Version:  3.0.x
 Keywords:  st_asgeobuf  |
-------------------------+---------------------------
 When I use `st_asgeobuf()` with WINDOW PARTITION it crashes server. Here
 is a simple example.

 {{{
 $ psql
 psql (13beta2, server 13.3)
 Type "help" for help.

 functions

 regression=> \x

 regression=> SELECT public.st_asgeobuf(NULL::pg_class, version()) over

 server closed the connection unexpectedly
         This probably means the server terminated abnormally
         before or while processing the request.
 The connection to the server was lost. Attempting reset: Failed.
