I traced a bug in our application down to this basic operation:

set timezone to 'US/Eastern';

select '11/02/2008'::timestamptz, '12:10'::time,
'11/02/2008'::timestamptz + '12:10'::time;

I have a date and a time stored separately and I want to combine them,
and use them in some timezone-aware calculations. When I add the time
12:10 to the date 11/2/08, I expect the timestamp "11/2/08 12:10" but
instead, I get "11/2/08 11:10".

It's probably not coincidence that daylight saving time rolls back one hour
on the morning of 11/2. Still, I would have expected the above behavior
when adding an interval to a timestamp, but not a time. Is the time being
cast to an interval before the add? Is there a better way to combine a
date with a time and get a timestamptz ? (the values are stored in the database, and are not literals as in my example)

If you are using functions take a look at plProxy. We created it after
finding out that dblink wasn't good enough for us in oltp environments.
There are also some security issues related to dblink that should be given
serious consideration.

As for replication SkyTools and Londiste are alternatives to Slony. SkyTools
should provide less management headaches.
