Hi

We had decided to drop our UUID generation function from DB in 4.2.1 and use the one provided by PG (using an extension)

Please note that once this patch [1] is merged , you will have to do the following steps in your env in order that it will continue working.

1) make sure that the postgresql-contrib is installed on your machine  (yum/dnf install postgresql-contrib -y)

2) run the following command from psql prompt while logging in with a DB admin (postgres) user

     a) DROP FUNCTION IF EXISTS uuid_generate_v1();

     b) CREATE EXTENSION "uuid-ossp";'

3) validate from psql prompt by :

# select *  from pg_available_extensions where name = 'uuid-ossp' and installed_version IS NOT NULL;

You should get the following result

-[ RECORD 1 ]-----+------------------------------------------------
name              | uuid-ossp
default_version   | 1.0
installed_version | 1.0
comment           | generate universally unique identifiers (UUIDs)

Please contact me for any questions or problems you encounter after this patch is merged to master.
