Adding a working example with Crate DB and panache

[mackerl]

• introduce CrateDbDialect ** specializing on differences to Postgres 14
  ** no sequences
  ** different timestamp creation (no prescision)
  ** map JSON as OBJECT(DYNAMIC)
  ** map array as array(elementTypeName) instead of ... elementTypeName array ** exclude unsupported features
• introduce CrateJsonType without casting (postgres default)
• show it on an example panache entity

Thank you so much for this effort, the PR is in a very good state, I left some mostly minor comments. Apart from those, I'd kindly ask you to include some more data types to the test Entity, and to please enrich the app with more actions, like updating, deleting, quering, etc.

Is it possible to also have some tests that assert the functionality? (apart from the app itself).

Hello,

tried to address the review items including a new junit test with testcontainers.

Thank you @mackerl!

Just left a couple of last comments. Could you please address them and squash your commits and then I can merge.

[mackerl]

done if I got everything correctly :)

Will just give a final check locally and merge soon.

@mackerl, Unfortunately running ./gradlew clean test doesn't work, nor ./gradlew quarkusDev

I get an error:

Caused by: java.lang.NullPointerException: Cannot invoke "com.fasterxml.jackson.databind.ObjectMapper.constructType(java.lang.reflect.Type)" because "this.objectMapper" is null

[matriv]

Additionally when attempting to run the Application I get:

ERROR: The LogManager accessed before the "java.util.logging.manager" system property was set to "org.jboss.logmanager.LogManager". Results may be unexpected.

@matriv I made a fix to the test - it seems a little bit weird, that Quarkus optimized the objectmapper out, but I prevented that now.
quarkusdev worked for me when specialising a correct database in application.properties - as I saw other test susing localhost:5432/testdrive I changed to that DB - unless there is a crateDB in quarkus devcontainers I see no way to create it on the fly.
