I have changed my applicaiton database from mysql to postgres since this the rights module is giving exception:
`CDbCommand failed to execute the SQL statement: SQLSTATE[42P01]: Undefined table: 7
ERROR: relation "authitem" does not exist
LINE 2: FROM AuthItem t1
^. The SQL statement executed was: SELECT
name,t1.type,description,t1.bizrule,t1.data,weight
FROM AuthItem t1
LEFT JOIN Rights t2 ON name=itemname
ORDER BY t1.type DESC, weight ASC `
I have reviewed the tables names and it's exactly the same 'case senstive'.
