After upgrading 3-node cluster from 10.5.8 to 10.5.9, I noticed that ALTER TABLE statements are not replicated. Change is visible only on initiator. No log message anywhere.
Later when I try to write a row in that table, other node fails:
I tried many different ALTER TABLE statements, without success. For example, CREATE TABLE works. All DML commands are also ok.
After downgrading back to 10.5.8, everything works.
