my last two times updating my mail server postfix started and didn't use
the definition of /etc/alias.dbm .
I ran newaliases && systemctl restart postfix and it saw them. Is there
anything in the upgrade that would maybe delete the db?

... part of my postfix's main.cf ...
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
