character varying array bug in 7.4.1

Could someone tell me if this bug is trivially reproducible or already solved 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 character varying arrays were getting a trailing space inserted into their last value. This appears to be the result of white space being misplaced during the INSERT/UPDATE command. If there is a space before the close-curly-brace, it gets appended to the last quoted value. When there is no space between the close-quotes and the close-curly-brace, the correct value is inserted. This behavior did not occur in 7.1beta5.

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

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

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

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