I came across such errors with an overpass instance.
To make a story short : You have to wipe out db files & re-import 

But what is interesting is to understand what happened and try to reduce the 
odds that it happens again.
In my case, the cause was an interrupted "update_database" process during 
diff 
applying.
kernel log files or syslog might confirm the cause. In my case, that was an 
"out of memory" condition in a OpenVZ container that killed the 
update_database process leaving some db files in an inconsistent state.

You can also improve debugging at :
https://github.com/drolbr/Overpass-
API/blob/master/src/bin/fetch_osc_and_apply.sh#L80

By redirecting update_database's output to some log file instead of /dev/null 
to increase your chances to find the culprit
