I decided to fix this table first - did so by creating a new table, running a
select from insert into and renaming the orig table to old_XXX and then
renamed the new table to the orig table's name.
I'll drop the orig table once I'm sure there are no data issues.
I'm planning to setup a new file system layout for the box(es) and try to do a
pg_dump | psql for the upgrade.
