 > Which PostgreSQL version is the reporting user using ?

 PostgreSQL 12.12 (Debian 12.12-1.pgdg110+1) on x86_64.
 PostGIS 3.3.1

 Database server has been updated only with binaries without SQL step :

 {{{
 SELECT postgis_extensions_upgrade();
 }}}

 Some database upgraded successfully some other not due to primary key
 missing.
 No explication why some are fine and other are not -_-
