PGAdmin - saving result sets from queries where one or more columns are of the type boolean

I've noticed this problem for a while, but haven't reported it. Sorry.

If you run a query in PGAdmin saving the results to disk and that query
selects one or more booleans it takes orders of magnitude longer for the
result set to save to disk that it does if you do not select those columns
in the query.

I've resorted to this work-around (when I remember it, and when I don't I
curse and go get a snack <grin>):

Instead of:

SELECT
col_a,
col_b,
is_a_boolean,
col_c
FROM
baz;

If I do this:

SELECT
col_a,
col_b,
CASE WHEN is_a_boolean = TRUE THEN 't' ELSE 'f' END
col_c
FROM
baz;

I avoid the problem.

Still, I'd rather not have to remember to write queries this way, so a fix
would be much appreciated. Thanks.
