     Works around postgresql bugs that make it impossible
     to delete multiple items in a single transaction
 
-    WARNING The Postgres version of these queries
-    assume that acs-messaging is only used by bboard
-    and general-comments,  and will delete entries made
-    by any other package.
-    If this poses a problem, revisit the oracle queries
-    and port the CONNECT BY query faithfully.
+    DRB fixed the assumption that only general-comments and bboard use acs_messaging
