Hello there!

I have two index  with a same field into them like this:

create index  numberfail on Events (numberfail);
and 
create index failtype on  Events (numberfail,eventtype);



then i ran explain analyze  and always  took the numberfail index but i wish  
the  failtype index;



this is the query:


SELECT * FROM events WHERE numberfail=194 AND eventtype='XXX';

What should i to do to force the use of failtypeindex????

I though maybe  if  i delete the index numberfail could works, but i don't know 
 if the  another program 
will fail  if the numberfail index does'nt exists.


well, thats all for the moment and i appreciate your time in reading this 
mail!!!
See you.
