> [Editing in progress]
> Change logical null from {{-1}} to actual {{NULL}}:
> - Change column {{CHARACTER_MAXIMUM_LENGTH}}.
> - Change column {{NUMERIC_PRECISION}}.
> - Change column {{NUMERIC_PRECISION_RADIX}}.
> - Change column {{NUMERIC_SCALE}}.
> Change column {{ORDINAL_POSITION}} from zero-based to one-based.
> Change column {{DATA_TYPE}} from short names (e.g., "CHAR") to specified names (e.g., "CHARACTER").
> Fix data type names "INTERVAL_DAY_TIME" and "INTERVAL_YEAR_MONTH" to "INTERVAL":
> - Change column {{DATA_TYPE}} to list "INTERVAL" for interval types.
> - Add column {{INTERVAL_TYPE}}.
> Move {{CHAR}} length from {{NUMERIC_PRECISION}} to {{CHARACTER_MAXIMUM_LENGTH}} (same as {{VARCHAR}} length):
> - Change column {{NUMERIC_PRECISION}} from length to logical null for CHAR.
> - Change column {{CHARACTER_MAXIMUM_LENGTH}} from logical null to length for CHAR.
> Move {{BINARY}} and {{VARBINARY}} length from {{NUMERIC_PRECISION}} to {{CHARACTER_MAXIMUM_LENGTH}} (same as CHAR and VARCHAR length):
> - Change column {{NUMERIC_PRECISION}} from length to logical null for BINARY and VARBINARY.
> - Change column {{CHARACTER_MAXIMUM_LENGTH}} from logical null to length for BINARY and VARBINARY.
> To correct ordinal position of some existing columns:
> - Add column {{COLUMN_DEFAULT}}.
> - Add column {{CHARACTER_OCTET_LENGTH}}.
> - Reorder column {{NUMERIC_PRECISION}}.
> Move date/time and interval precisions from {{NUMERIC_PRECISION}} to {{DATETIME_PRECISION}} and {{INTERVAL_PRECISION}}:
> - Change column {{NUMERIC_PRECISION}} to logically null for date/time and interval types.
> - Add column {{DATETIME_PRECISION}}.
> - Add column {{INTERVAL_PRECISION}}.
> Implement {{NUMERIC_PRECISION_RADIX}}:
> - Change column {{NUMERIC_PRECISION_RADIX}} from always logically null to appropriate values (2, 10, NULL).
> Add missing numeric precision and scale values (for non-DECIMAL types):
> - Change NUMERIC_SCALE from logical null to zero for integer types.
> - Change NUMERIC_PRECISION from logical null to precision for non-DECIMAL numeric types.
