The best way change the output style in general is a stored procedure.
However, with booleans it's simple enough that you could write it out inline
if you want:
------------------------------------------------------------------------------
jdavis=> create table b(a bool);
CREATE
jdavis=> insert into b values('t');
INSERT 67682 1
jdavis=> insert into b values('f');
INSERT 67683 1
jdavis=> select case when a then 'YES' else 'NO' end from b ;
case
------
YES
NO
(2 rows)
--------------------------------------------------------------------------------
The case statement basically just special cases the two values. In this case
it of course changes 't' to 'YES' and 'f' to 'NO'.
You could also make a SQL function out of it no problem:
jdavis=> create function myfn(bool) returns text as 'select case when $1 then
''YES'' else ''NO'' end;' language 'sql';
Then just use that in your selects:
jdavis=> select myfn(a) from b;
myfn
------
YES
NO
(2 rows)
