+This files describes API changes in the logstore_database code.

+=== 3.4 ===
+* PostgreSQL connections now use advanced options to reduce connection overhead.  These options are not compatible
+  with some connection poolers.  The dbhandlesoptions parameter has been added to allow the database to configure the
+  required defaults. The parameters that are required in the database are;
+    ALTER DATABASE moodle SET client_encoding = UTF8;
+    ALTER DATABASE moodle SET standard_conforming_strings = on;
+    ALTER DATABASE moodle SET search_path = 'moodle,public';  -- Optional, if you wish to use a custom schema.
+  You can set these options against the database or the moodle user who connects.
