No, strike that, I remember the discussion now. The pre-8.2 code is
correct on its own terms, which is that it's telling you what size
number you tried to put in:
regression=# select '123123123123123.2'::numeric(12,2);
ERROR: numeric field overflow
DETAIL: The absolute value is greater than or equal to 10^14 for field with precision 12, scale 2.
regression=# select '12123123123123123.2'::numeric(12,2);
ERROR: numeric field overflow
DETAIL: The absolute value is greater than or equal to 10^16 for field with precision 12, scale 2.
regression=#
Bruce and some other people thought this was confusing, so it's been
changed for 8.2.
