[SR-Users] upgrade kamailio 4.4.x-to-5.0.0 - PostgreSQL migrations

[Ovidiu Sas]

Hello Giovanni,

You can check the postgres db scripts for each kamailio version under
utils/kamctl/postgres.
There you have the scripts for creating the postgress db tables.
You can see the exact differences between versions by comparing the
relevant files.
This is how I double check the db changes between upgrades :)

Hope this helps,
Ovidiu
