Ebean PGvector

[Ryszard Trojnacki]

Hi Rob,

I have done some work to make Ebean work with pgvector extension for Postgres.

So far I have:

1. Extended ebean-datasource module to add posibility to register PGvector types.

2. Added module for main ebean.

Ad. 1. This just adds a new listener that allows to do something with newly created connection for example do: PGvector.registerTypes(connection);

Overall I'm not sure if this is the right way to do this.

This allows for manually changing new connection settings. But for a module this makes no sens. The module should be initalized without extra manually written code like: io.ebean.core.type.ExtraTypeFactory that is in META-INF/services.

Should I change this to ServiceLoader mode?

Ad. 2. I have added a module ebean-pgvector that adds scalar types, but to do that I had also to:

- add extra types: ExtraDbTypes,
- add types to enum DbType,
- register new types in PostgresPlatform.

And now when everything is done I'm trying to run tests, but I have problem with this.

I have added PGvectorSetup and registered it in PlatformAutoConfig. I have setup this in application-test.yml, but it (Docker container) doesn't start.

What I'm missing?
