Returns the default database schema for the DBI table_info command.
Inheriting from DBIx::DBSchema::DBD will provide the default empty string.

+
+Optional callback for driver-specific overrides to SQL column definitions.
+
+Should return a hash reference, empty for no action, or with one or more of
+the following keys defined:
+
+effective_type - Optional type override used during column creation.
+
+explicit_null - Set true to have the column definition declare NULL columns explicitly
+
+effective_default - Optional default override used during column creation.
+
+effective_local - Optional local override used during column creation.

+
+Optional callback for additional SQL statments to be called when adding columns
+to an existing table.
+
+Should return a hash reference, empty for no action, or with one or more of
+the following keys defined:
+
+effective_type - Optional type override used during column creation.
+
+effective_null - Optional nullability override used during column creation.

+Optional callback for overriding the SQL statments to be called when altering
+columns to an existing table.
+
+Should return a hash reference, empty for no action, or with one or more of
+the following keys defined:
+
+sql_alter - Alter SQL statement(s) for changing everything about a column. Specifying this overrides processing of individual changes (type, nullability, default, etc.).
+
+sql_alter_type - Alter SQL statement(s) for changing type and length (there is no default).
+
+sql_alter_null - Alter SQL statement(s) for changing nullability to be used instead of the default.
