I can't give you the answer, but maybe it would guide you in the right direction.
I had some issues with build-schema some time ago, with symfony 1.0 + propel + mysql db (task was to build admin app in sf for a non sf project). All I remember is that, all the problems were resolved by using Yog (db tool, you can get community edition for free - not sure if this version has all you need) to make some db changes (indexes / relations most likely, but as I say I don't remember;( ).
