I just ran into this yesterday also. I was trying
select * from foo where expired IS TRUE
and the index was not used, but when I switched it to expired = true it worked... Very frustrating bug.. wasted about 3 hours planning and analyzing the simple query.

Hi all,
is it normal that in a select like:
select * from foo where expired;
the index on expired is not used?
If I rewrite that query:
select * from foo where expired = true;
then the index is used!
I'm using postrgres 7.4.2
