--------------------------------------------
[~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 uses create table if not exists for the postgres script

> 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.
