update_count is just the count of the records for a tx. To calculate onchain fees
for an account we must sum all credits vs debits. We don't need to GROUP BY update_count
nor ORDER BY update_count since it is just a running index of updates to this tx.
Any file in this directory which is executable and whose name only
consists of alphanumeric characters, space, '.', '-' or '_' will be
automatically loaded when lightningd starts (unless suppressed with
commandline options).
