Hi there,

I'm very new to the Yesod project, so I do apologise if I've missed something here. I've really enjoyed reading about this framework and I was experimenting with setting up the database (Postgres) tables in config/models; after setting up some models, I noticed that the primary key was Int4 but arbitrary columns set as Int would be created as Int8.

I took a look around the codebase and spotted that "SERIAL" is defined on line 491 of Postgresql.hs. The serial column type creates an Int4 column, whereas bigserial/serial8 creates an Int8 column. It's currently causing me problems when defining foreign keys as the column types aren't matching.

I took a look around the documentation and found nothing about this in the wiki or the Yesod Web Framework Book. I took a look around the existing issues and issue #455 looked vaguely similar, but I wanted to raise a new query just in case. Is there a configuration option that I've missed here or some documentation that I've missed?

Thanks,
connrs.
