Ensures that the database's types have been read into holder, the catalog a connection to it reads. This method is internal to the driver.
The line this writes names the dictionary a Relational-Object Mapping Engine, which is the accurate description as well as the joke: a catalog read onto Kotlin types is the whole of what Octavius maps, with no session tracked, nothing lazy-loaded and nothing dirty-checked either side of it. Which is to say it is not an ORM - the letters only look that way from the other end.
