schema change: allow recording of log_messages with worker_id=NULL

sql/patch_2013-07-09.sql

+
+    -- Relax the restriction that each log_message entry has to have a non-NULL worker_id; allow a NULL there:
+ALTER TABLE log_message  MODIFY COLUMN worker_id INTEGER DEFAULT NULL;
+
+    -- Allow log_messages from 'SEMAPHORED' jobs:
+ALTER TABLE log_message MODIFY COLUMN status ENUM('UNKNOWN','SPECIALIZATION','COMPILATION','SEMAPHORED','READY','PRE_CLEANUP','FETCH_INPUT','RUN','WRITE_OUTPUT','POST_CLEANUP','PASSED_ON') DEFAULT 'UNKNOWN';
+
+    -- LEFT JOIN with worker so that entries with worker_id=NULL would still be shown:
+CREATE OR REPLACE VIEW msg AS
+    SELECT a.analysis_id, a.logic_name, m.*
+    FROM log_message m
+    LEFT JOIN worker w USING (worker_id)
+    LEFT JOIN job j ON (j.job_id=m.job_id)
+    LEFT JOIN analysis_base a ON (a.analysis_id=j.analysis_id);
+
+    -- UPDATE hive_sql_schema_version
+UPDATE hive_meta SET meta_value=50 WHERE meta_key='hive_sql_schema_version' AND meta_value='49';
