onedb upgrade from 5.12 -> 6.0 fails with PostgreSQL

[VMGuy]

Description
When running onedb upgrade -v -t postgresql -S localhost -u oneadmin -p <PASSWORD> -d opennebula it returns with this error on PostgreSQL:

undefined method `delete_idx' for #<BackEndPostgreSQL:0x000055cbdd5894f0>
/usr/lib/one/ruby/onedb/onedb.rb:302:in `upgrade'
...

I tried commenting this call in onedb.rb but then I hit the next error message:

PG::UndefinedObject: ERROR:  type "mediumtext" does not exist
LINE 1: ...(oid INTEGER PRIMARY KEY, name VARCHAR(128), body MEDIUMTEXT...
                                                             ^

To Reproduce
Install OpenNebula 5.12 with PostgreSQL.
Upgrade to 6.0 using opennebula-migration-community_6.0.0-2.ee_all.deb

Expected behavior
DB upgrade should work as it does with MySQL/MariaDB.
