There is a CentOS8-stream version which solves the problem but I cannot use that in the office. I will probably have to wait for another month before OL8 has everything that I need in its repositories. Now, the question is what kind of an impact will running without llvm-jit have? According to the links below, llvm-jit effects are quite spectacular:
When JIT was used on very large query with a lot of CASE expr, then JIT has a positive effect about 50%. On usual large queries, the effect of JIT was about 20%. Unfortunately, JIT is sensitive to estimation, and the JIT sometimes increases seconds to queries, although without JIT this query is executed in ms. When you use a query that can be well calculated in parallel, then positive effect of JIT is less.

Thanks Pavel, you answered my question. I'll wait with the upgrade.
