Alter column varchar(n) via updating pg_attribute

The last time this was asked about
(http://archives.postgresql.org/pgsql-admin/2010-02/msg00189.php), 9.0
was still alpha.

Is there any reason to suspect that direct pg_attribute manipulation to
expand a varchar(n) column might not play nice with streaming
replication/hot standby?  (Naturally I'm also in the process of testing).

Thanks,
Geoff
