the default kamailio.cfg is aiming to offer a starting point for building more complex configuration/SIP routing policies, not to offer all the options we support in Kamailio. MySQL is provided there to show how to connect to database, being chosen because it was the first database connect module that was developed and it is kept because it is still very popular. You are more than welcome to add a sample config of using postgress, which can be placed somewhere in the misc/examples/. Making the default config too complex may result in "scaring" the people trying to use Kamailio for first time.
Using string UUID instead of the auto-increment integer id it will break at least lcr and msilo, iirc. Most of the modules do not use id column, but some do it. Siremis, the web management interface is also using the id field, but it doesn't support Postgres at this moment.
If you have some Python knowledge (and spare time), maybe you can help adding support for it in kamcli:
* https://github.com/kamailio/kamcli
kamcli aims to be a more modern alternative to kamctl/kamdbctl (e.g., better input validation, flexibility in output formatting, internal interactive shell with auto-completion, ...), eventually replacing them in the future. So far I was focusing on MySQL, being the database type I use. Most of the commands should just work for Postgres, because db operations are done using SqlAlchemy package, but a few commands (from the kamcli db ... subcommand) use the cli tool of the database system. At the end these can be skipped, iirc, also for kamctl, some of the corresponding subcommands are only for mysql (like kamctl db connect), but testing and seeing if it works or not with Postgres or CockroachDB would be appreciated.
Cheers,
Daniel

Henning,
So, for the default config, it only has the option for: WITH_MYSQL. I was wondering if a WITH_PGSQL would be accepted.
As for the kamdbctl scripts, there are a few things I’ve noticed:
I would prefer UUID vs SERIAL. This actually is a little more annoying when dealing with the SEQUENCE entity in Postgres. The only change required, is to load the pgcrypto extension and switch to uuid instead of SERIAL. I have a tracking branch here:
The other reason is that for cockroachdb, using gen_random_uuid() is documented to be more efficient (in addition to being a preference).
As for cockroachdb, I have a tracking branch (based on the uuid branch) that seems to be working well:
So far, the only issue in the creation/managment of the schema is: CREATE FUNCTION. But it looks like maybe concat() and random() are already supported by cockroackdb: https://www.cockroachlabs.com/docs/stable/functions-and-operators.html. I will have to dig deeper into the lcr module to see where/if this is an issue.
Thanks!

Hi Noah,
if you find something that does not work with the default PostgreSQL schema from kamdbctl, create an issue. It some cases it is just a matter of formatting and it can work for PostgreSQL and CockroachDB. This is probably the easier path, from an maintenance point of view.
What do you mean by default configuration?
Cheers,
Henning

Henning,
Thanks for the reply! I am testing away. I will update with my findings.
That being said, some things might be slightly different. Should I add a cockroachdb option to the kamdbctl and default configs as a PR?

Dear Noah,
it was probably not discussed on the public list, at least I don't remember it. Cockroachdb claims to be compatible with PostgreSQL, so it should work with this DB Kamailio module.
If you encounter issues, report on this list, or open a bug report if its something related to problems in the Kamailio db_postgres module.
Cheers,
Henning

Has anyone been down this path before? We are trying to test this out and the results are pretty promising so far.
I realize the lack of Stored Procedures and Triggers make this untenable for many Postgres based implementations.
Thanks!
