Hm, I thought I tested that same case, but I must've messed up somehow.
Anyway, the code seems to be intentionally reporting the log10 of the
actual input value, not the limiting log10 for the field size. This
behavior goes at least as far back as PG 7.0, so I'm disinclined to
change it. We could talk about altering the message wording though,
if you have a suggestion for something you'd find less confusing.
Pre-7.4 versions say
ERROR: overflow on numeric ABS(value) = 10^9 for field with precision 9
scale 3
so it looks like we just fixed the grammar during the 7.4 message
wording cleanup, without reflecting about whether the meaning was clear.
Yes, this message clearly needs help. Here is what I developed:
test= CREATE TABLE foo (n numeric(9,3));
CREATE TABLE
test= INSERT INTO foo VALUES (1000);
ERROR: numeric field overflow
DETAIL: A field with precision 9, scale 3 must have an absolute value
less than 10^6.
and the 10^6 is based on the max digits to the left of the decimal
point, not the input value.
