"Official" support in DBI for enum columns?

[mohawk2]

Is there any appetite for having DBI support "enum" columns on column values? It's a pity that MySQL, PostgreSQL, SQLite, and probably others that support such, each have to either not report them through column_info, or have to do their own thing e.g. mysql_values.

It seems to me that optional "if supported" columns in the return from column_info would do: IS_ENUM (a boolean), and ENUM_VALUES (an array-ref).

I'll be happy to make PRs on DBI and relevant DBDs.

Also, a similar question about auto-increment values as they apply to columns, rather than to types.
