--------------------------------------------

[~ngangam] Can you please take a look? I will wait for precommit to complete but I don't think it tests schema changes anyway currently.

> HIVE-13076 addes a new table to the schema but the patch script uses {{CREATE TABLE IF NOT EXISTS}} syntax to add the new table. The issue is that the {{IF NOT EXISTS}} clause is only available from postgres 9.1 onwards. So the script will fail for older versions of postgres.
