Peter Smith mentioned to me off-list that the names of conflict types
'update_differ' and 'delete_differ' are not intuitive as compared to
all other conflict types like insert_exists, update_missing, etc. The
other alternative that comes to mind for those conflicts is to name
them as 'update_origin_differ'/''delete_origin_differ'.

The description in docs for 'update_differ' is as follows: Updating a
row that was previously modified by another origin. Note that this
conflict can only be detected when track_commit_timestamp is enabled
on the subscriber. Currently, the update is always applied regardless
of the origin of the local row.

Does anyone else have any thoughts on the naming of these conflicts?
