Immediately after sending this I realized that timestamptz suffers from the same problem. Attached is an updated patch that fixes timestamptz too.
Thanks,

Hi all,
Attached is a patch that fixes some overflow/underflow hazards in `timestamp_pl_interval`. The microseconds overflow could produce incorrect result. The month overflow would generally still result in an error from the timestamp month field being too low, but it's still better to catch it early.
I couldn't find any existing timestamp plus interval tests so I stuck a new tests in `timestamp.sql`. If there's a better place, then please let me know.
