UDF functions from system.functions table is not replicated when starting a new node

[xpolb01]

We have an issue where sometimes one of our Clickhouse nodes goes down and we need to bring in a new node, everything is being replicated as expected except those user-defined functions. To solve it we have to go through our migrations, gather those and execute them separately on the new node. What would be the best way to manage this?

How to reproduce

1. Add UDFs to system.functions table
2. Delete the pod with one of the replicas
3. On the new node there is not going to be UDS in the system.functions table

Expected behavior

I would expect UDFs to be present in the system.functions table
