24507	Add the possibility to create only one index on CharField	Rodolphe Quiédeville	nobody	"As describe in the doc adding a db_index=True on CharField automatically create 2 indexes on some backends to speedup LIKE queries. But in some case the second index is not necessary when you know you always lookup on the entire string. 
Having a new option too only create simple index may be a good improvement, actually on high volume database we need to maintain our indexes outside of Django cause of that.
