     *Erol Fornoles*
 
+*   PostgreSQL: Fix db:structure:load silent failure on SQL error
+
+    The command line flag "-v ON_ERROR_STOP=1" should be used
+    when invoking psql to make sure errors are not suppressed.
+
+    Example:
+
+        psql -v ON_ERROR_STOP=1 -q -f awesome-file.sql my-app-db
+
+    Fixes #23818.
+
+    *Ralin Chimev*
