character varying array bug in 7.4.1

Could someone tell me if this bug is trivially reproducible or already solv=
ed before I do a lot of needless documentation on it?

I upgraded from 7.1beta5 to 7.4.1 recently, and I noticed that many of my c=
haracter varying arrays were getting a trailing space inserted into their l=
ast value. This appears to be the result of white space being misplaced dur=
ing the INSERT/UPDATE command. If there is a space before the close-curly-b=
race, it gets appended to the last quoted value. When there is no space bet=
ween the close-quotes and the close-curly-brace, the correct value is inser=
ted. This behavior did not occur in 7.1beta5.

Here's a test I did to show the problem:

test=3D> update nametable set names =3D '{ "arf" }' where id =3D 1;
UPDATE 1
golem=3D> select id, names from nametable where id =3D 1;
 id | names=20
----+------------------
  1 | {"arf "}
(1 row)

golem=3D> update nametable set names =3D '{"arf"}' where id =3D 1;
UPDATE 1
golem=3D> select id, names from nametable where id =3D 1;
 id | names=20
----+------------------
  1 | {arf}
(1 row)

I'll be glad to document this further if needed.
