 MISC ITEMS THAT CAME UP
 
+todo: use explain to determine if indexes are being used
 todo: All indexes in db sb named starting with idx_ instead of just the table name, so just prepend idx_ to every index
 todo: foreign keys are not indexed by default in the referencing table (the one who references)
 	take a look and see if any should be indexed when doing above
