There are no built-in features to limit numeric values in the described manner. You can create and use a function to implement this behavior:<\/p>\n

create or replace function limited_numeric(val numeric, prec int, scale int)\nreturns numeric language sql immutable as $$\n    select least(mx, val)\n    from (\n        select format('%s.%s', repeat('9', prec- scale), repeat('9', scale))::numeric as mx\n    ) s\n$$;\n<\/code><\/pre>\n
Example usage:<\/p>\n
insert into products \nvalues (1, 'article 1', 'name 1', limited_numeric(12345678, 10, 3))\nreturning *;\n\n id |  article  |  name  |  quantity   \n----+-----------+--------+-------------\n  1 | article 1 | name 1 | 9999999.999\n(1 row)\n<\/code><\/pre>\n
There is no kind of constraint to automatically accomplish this. Neither you can use a trigger for this because numeric value overflow is checked before any trigger is executed.<\/p>\n<\/p><\/div>\n
