New description:

 I ran ST_ConcaveHull on OSM data in Senegal using PostGIS 3.3 (on PG 15),
 and it worked perfectly. However, when I tried with a different dataset
 (OSM data over the state of Bahia, Brazil), it caused PostgreSQL to crash
 with the following message: "server closed the connection unexpectedly
         This probably means the server terminated abnormally
         before or while processing the request."
 I updated PostGIS to version 3.61 this morning (still on pg 15), and now
 even Senegal crashes.
 Are there any plans in place to prevent these crashes, or at least to
 identify the objects that cause them?
 Or are these crashes related to PG15, and will a more recent version avoid
 them?
