If you have installed the contrib modules (oid2name specifically), you
can use that to get the name of the bloated database:

oid2name | fgrep 607471

If the name of the database doesn't give you any insight, then look
for large files in the directory base/607471 that whose names all
start with the same digits and use oid2name to get the names of the
relations for those files.

oid2name -d <name of database> -o <base name of large files>

Cheers,

Jeff
