           |  |  | 9 | * PostgreSQL connections now use advanced options to reduce connection overhead.  These options are not compatible
 | 
        
           |  |  | 10 |   with some connection poolers.  The dbhandlesoptions parameter has been added to allow the database to configure the
 | 
        
           |  |  | 11 |   required defaults. The parameters that are required in the database are;
 | 
        
           |  |  | 12 |     ALTER DATABASE moodle SET client_encoding = UTF8;
 | 
        
           |  |  | 13 |     ALTER DATABASE moodle SET standard_conforming_strings = on;
 | 
        
           |  |  | 14 |     ALTER DATABASE moodle SET search_path = 'moodle,public';  -- Optional, if you wish to use a custom schema.
 | 
        
           |  |  | 15 |   You can set these options against the database or the moodle user who connects.
