There seems to be a problem with exporting of 'db-null type:
CL-USER> (pomo:sql (:create-table foo ((age :type (or db-null integer) :default :null)))) "CREATE TABLE foo (age OR NOT NULL DEFAULT NULL)" =========> error!
CL-USER> (in-package :pomo) #<The POSTMODERN package> POMO> (pomo:sql (:create-table foo ((age :type (or db-null integer) :default :null)))) "CREATE TABLE foo (age INTEGER DEFAULT NULL)" POMO>
