Upgrading more than 2 releases isn't supported, so I don't believe the 
19.05 slurmdbd will have the code in it to upgrade tables from earlier 
than 17.11.

People still on 17.02 and earlier will have to go to an intermediate 
release to get their tables properly updated (and as you say, either 
apply your patch or migrate their MySQL server to a box running a more 
recent version of MySQL - it doesn't have to be on the same system 
running slurmdbd).

All the best,
