Well, it would've immediately (rather than the several minutes it took)
given away the problem if it read something like:
ERROR: overflow caused by cast of double precision value to numeric
without sufficient precision, scale (15, 6)
or even, depending on how much detail is available or how much worth
assigned to error reporting:
ERROR: a double precision value requiring at least precision 16 cannot
be cast to a numeric value with precision 15, scale 6.
i understand the need for balancing correctness with readability,
though. if there's anything technically incorrect about either of my
proprosals, they clearly should not be used.
i'm usually a fan of breaking error messages down as far as the details
will allow them to be correctly broken down.
in this situtation, it seems like it is this specific cast (double
precision -> numeric) in this specific scenario (insufficient precision)
that generates the error.
unfortunately, i haven't read the code... :(
