--------------------------+-------------------------------------------------
 [8922], the fix for #7431, introduced an unnecessary line that adds
 wp_postmeta.meta_value to the list of selected fields.

 Talking to !AaronCampbell, the author of the above patch, in IRC confirmed
 my hunch that it was unintentional.

 If you're querying by meta_value, then you already know the meta_value
 value.  If you're querying by just meta_key, then you will (in theory) not
 get back all meta_values because there will be only one entry per post
 (see #9167).  So meta_value is either unnecessary or unreliable as Loop
 query data.
