Error Message: 42704: unrecognized configuration parameter "sql_mode"
When I run the following in my Postgres database, it gives Message
42704: unrecognized configuration parameter "sql_mode".
**SET sql_mode='PIPES_AS_CONCAT';
SELECT 'select MAX(LENGTH('||COLUMN_NAME
|| ')), ''' ||COLUMN_NAME || ''' FROM test UNION'
FROM INFORMATION_SCHEMA
.COLUMNS
WHERE TABLE_SCHEMA
='test'
AND TABLE_NAME
='test';**
Can someone help what is wrong with the query?
