Hi experts I tried to upgrade one of my databases from v11 to v14. But I faced following error during upgrade: “System catalog modifications are currently disallowed” This is regarding to postgis extention that is installed in pg_catalog, apparently I can’t move extention from pg_catalog to public schema. In the other hand I can’t drop postgis extention as it uses frequently in different tables. Is there any option like “allow_system_table_mods” for pu_upgrade? Any idea how can I sort this issue? Regards Abbas
