Sure. Timestamp features were based on abstime features (at least partly
to support conversions to the newer type), and date features are from
date. "Infinity" for timestamp (or date) is not as compelling as it is
for abstime, which has a very limited range. I've been a fan of those
nifty features, but am not sure they are really necessary now that
PostgreSQL supports NULLs for pass by value types and supports a wider
range in the timestamp type (date has always had a wide range).
