> If two separate Phoenix connections try to upgrade Phoenix from v4.7 to 4.8.1
> then second connection fails with the following exception. This happens even
> if second connection is couple of seconds apart but within upgrade window.
> This is likely to happen in situation where pool of client machines all get
> upgraded to latest Phoenix version. After this exception, all clients will
> cease to work with undefined column exception due to restore/aborted upgrade.
