Goal Find base table columns with DECIMAL (p, s) or NUMERIC (p, s) type and make sure that precision p and scale s are not too big or too small.
Notes DECIMAL and NUMERIC are synonyms in PostgreSQL and thus, internally, the type name is always NUMERIC.
Type General Overview of some aspect of the database.
