@Goldmensch this is what I asked in original issue: how could I know database type in JdbcQueryStatement?

@Goldmensch I doubt that micronaut could generate semantically correct query for null value or I should change query completely

**To confirm that fix is actually working** _Without Fix:_ ``` ./gradlew data-jdbc:test --tests=*UUIDSpec ... SUCCESS: Executed 19 tests in 1m 20s ./gradlew data-r2dbc:test --tests=*UUIDSpec ... SUCCESS: Executed 19 tests in...

I checked postgresql14 too, still can't reproduce

@Goldmensch correct, something could be wrong with native queries I'm struggling to debug specific method ``` Message: Multiple possible bean candidates found: [io.micronaut.aop.InterceptorRegistry, io.micronaut.aop.InterceptorRegistry ```

@Goldmensch negative, criteria works too. Could it be related to kotlin which I originally used to wrote a case? The most interesting part that I don't see inserts in log...

Error when I'm trying to run a single spec test in IntelliJIDEA looks exatly like this: https://github.com/micronaut-projects/micronaut-core/issues/6579

@Goldmensch I'm running in terminal `./gradlew data-jdbc:test --tests=PostgresUUIDSpec` and don't see queries except create tables

@Goldmensch Ok, I found logs in data-jdbc/build/test-results/test/TEST-io.micronaut.data.jdbc.postgres.PostgresUUIDSpec.xml

Driver change to the latest version 42.5.0 does not fix the problem in the demo project.
