Savepoint/Nested Transactions support?

[canni]

I couldn't find any info on this, does exposed support SAVEPOINTs / nested transactions?

It's really helpful when testing and your DB (i.e. Postgres/SQLite) supports transnational DDL

Only through using a raw connection. I.e. you can use something like:

fun withSavepoint(errorMsg: ((Exception) -> String)? = null, body: () -> Unit)  {
    with(TransactionManager.current()) {
         val savepoint = connection.setSavepoint()
        try {
            body()
            connection.releaseSavepoint(savepoint)
        } catch (e: Exception) {
            connection.rollback(savepoint)
        }
    }
}
