Can you check if you had any vacuums running at the time of crash?

It might be in logs, something like:
WARNING: terminating connection because of crash of another server process
DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.
HINT: In a moment you should be able to reconnect to the database and repeat your command.
STATEMENT: vacuum

if yes - how many vacuum jobs there were?
