/**

Some notes...

drupal docs don't list a bool type, but it might be nice to use rather than 'tinyint'
note however that we use bitfields and things as well in tinyints

decimal <-> numeric

timestamps... how to specify?
fulltext indexes?
got one or two things wanting a custom charset setting on a field?

foreign keys are kinda funky...
    those specified in inline syntax (as all in the original .sql) are NEVER ENFORCED on mysql
    those made with an explicit 'foreign key' WITHIN INNODB and IF there's a proper index, do get enforced
    double-check what we've been doing on postgres?
