What is the data type of that column?

Not sure what I'm looking at, but screenshots 1 and 2 say precision=19
and scale=18 which would be numeric(19,18). But value 311116655.63
shown in the error message requires a precision that is at least 9
digits larger than the scale:

regress=# select '311116655.63'::numeric(19,18);
ERROR: numeric field overflow
DETAIL: A field with precision 19, scale 18 must round to an absolute value less than 10^1.
regress=# select '311116655.63'::numeric(27,18);
numeric
