Short Description
case and LIMIT not working together

Long Description
PostreSQL 7/1/3 i686-pc-linux-gnu compiled by GCC 3.0

when I count ( case ... ) LIMIT

The count is from the entire table not from the LIMIT

in the below example the count is returned with the
same value in all three statements

Sample Code
select count( case when b='T' then 1 else null) from test limit 50;

select count( case when b='T' then 1 else null) from test;

select count(*) from test where b = 'T';
