I would like to safely clean duplicate field revision data. This field_revision_(field_name) data not associated with nodes, but the relation entities.
I'm using the relation module. I'm bumping up against the problem outlined here: https://www.drupal.org/node/1530164
I have a lot of relations on my site linking different entities. My field_revision_endpoints table is growing quite large. The issue mentions as a work around, he uses a sql script to clear out the old revisions. I did some googling on info for deleting revisions, but I'll I have come up with is results relating to deleting node revisions.
Is it safe to simply delete rows out of field_revision_endpoints?
