Query 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 about the query: | DECIMAL and NUMERIC are synonyms in PostgreSQL and thus, internally, the type name is always NUMERIC. |
Query type: | General (Overview of some aspect of the database.) |
