#6127: PostgreSQL 20 doesn't work against 3.7.0
---------------------+---------------------------
 Reporter:  robe     |      Owner:  pramsey
     Type:  defect   |     Status:  new
 Priority:  medium   |  Milestone:  PostGIS 3.7.1
Component:  postgis  |    Version:  master
 Keywords:           |
---------------------+---------------------------
 Both debbie and gha are registering errors because we haven't flipped
 their following of PostgreSQL master and amster recently flipped to
 PostgreSQL 20dev.

 That said recent changes have deviated enough from 19 to make it break
 with this error.

 }}}

 I don't think it's worth fixing for 3.7.0 release since we'll probably
 have many more breakages so pushing to 3.7.1
