jOOQ version is outdated

It's unclear whether this is necessary to update and when, however this project uses jOOQ `3.16.x` whereas `3.17.x` and `3.18.x` are available, but have breaking changes. At some point it may be necessary to update.

No files, tests, or entry points are named. First determine whether upgrading jOOQ is required, then review the 3.17 and 3.18 breaking-change notes and define compatibility checks for H2, PostgreSQL, and MySQL before an upgrade can be considered done.
