Doh! Yup, is recognizable. It looks like some PHP serialized output:

png%";i:84;s:24:"%InfoToolIconActive.png%";i:85;s:29:"%InfoToolIconHighlighted.png%";i:86;s:26:"%InfoToolIconInactive.png%";i:87;....

We do store serialized PHP objects like the above one in the database,
so it's probably not a mail spool.

Thank you for you guidance. I've done that and hope the running pg_dump
goes through fine.
