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
