Agreed.  Mea culpa.
Based on your comments, I dug deeper into my term_node table and I
actually had several duplicate tid-nid pairs.  Not sure how that

Commit# 14491 modifies the term_node table to make both tid and nid
primary keys. That is,
ALTER TABLE term_node ADD PRIMARY KEY (tid,nid);
However, I've got nodes (as referenced by nid) that have multiple
taxonomy terms associated with them (as reference by tid). As such, the
node_term table with have duplicate entries of nid, one for each term
(tid) that the node is associated with. I don't believe you can make a
column a primary key if the values are not unique can you?

It's a multiple column PRIMARY KEY and it will apply unless you have the
same nid-tid pair twice which shall not happen...
