Sigh. Ok, I settled on:<br /><blockquote><tt>select '1987-01-29'::timestamp + interval '21 years' > now();</tt><br
/></blockquote>Which is closer to what I wanted anyway (this was all about determining who was under 21 years old). 
Thisat least should be robust over leap years.<br /><br /><br /> Tom Lane wrote:<br /><blockquote
