The queue ID is always logged after it has been assigned. Also set
enable_long_queue_ids = yes
in any supported Postfix version, to ensure that queue IDs are
unique.

No, don't do that.

The first line isn't really specific to queue ID 745EC6AC49, but the
following line mentions it. You could grep 745EC6AC49, but the best
choice is usually to use a pager like less, and search using its
search function.
If/when 745EC6AC49 is finally delivered or permanently bounced for
some reason such as maximal_queue_lifetime, the queue ID will be
mentioned in logs describing the final disposition.
