         HOW TO INDEX
         https://www.postgresqltutorial.com/postgresql-indexes/postgresql-create-index/
-        AyaNova does a lot of name fetching so any tables that contain a lot of columns in addition to the name will benefit from a compound index on (id,name)
+        
 
         Other indexes should be created with care and after a huge load and integration test periodically look for unused indexes and see how they are performing
