So far I can confirm this at least for MySQL.

I had a short look on PostgreSQL and noticed that there is no support 
for ENUMs, neither directly (AFAIK ENUM is quite new for Pg) nor by a 
CHECK constraint on varchar. But since I don't use Pg I actually don't 
care much.

Simply don't specify the size for date/datetime/tim fields.
Can be counted as a bug at least for MySQL and SQLite (Pg seems OK).

  xyz => {
    data_type => 'enum',
    extra => {list => [qw(foo bar baz)]}
