This seems significant:
Warning: Could not create server TCP listening socket *:6379: bind: Address already in use
I think Redis is expected to run on port 6379.
Could not being able to create the Redis server cause issues with migrations?
Error: relation "summary_sections" already exists
For some reason the migration to create the summary_sections table is getting run again. Are there any other duplicate table errors in your logs?
I guess the other question is, do you have a recent backup file?
