Your previously-shared log output had no useful information--to the 
point of not having any of the information that should appear for any 
database upgrade failure--so i can't do anything other than guess what 
may be happening.

So, is this an attempt to create a brand-new, empty database schema (as 
opposed to an actual upgrade)?  If so have you actually let mythtv-setup 
fail and then immediately restarted mythtv-setup to see if it succeeds?

A couple of versions ago, i was going to roll up the changes to the 
database schema into a new database initialization, but I stopped 
because I found that some changes to the startup sequence had (as pretty 
much every single time anyone has made them) once again broken initial 
database creation.  I didn't have much time to work on the issue, so I 
never fixed it (and am 99% positive the issue still exists), but I did 
notice that while the first start of mythtv-setup would create a schema 
and then fail to upgrade it to current, a restart of mythtv-setup 
afterwards would successfully upgrade it to current.  So since it was 
possible to successfully create a new initial database (by simply 
restarting mythtv-setup after it failed--actually, didn't attempt and 
reported as failed--the upgrade to current schema), it wasn't that 
critical an issue.  If that's the issue you're seeing, just restart 
mythtv-setup and let it successfully upgrade your database.
