Are there any reasons why the data migration plugin always converts the type
of the field to INT8? This can be a bit annoying if there are foreign keys
of type INT4 which refers to the fields. The default behaviour in PostgreSQL
is to create new serial columns of type int4.
I suggest you keep the type of the field, and only change it only according
to the type map.
Another small annoyance is that the plugin uses "_key" to name the
sequences. Could this be changed to "_seq" to be consistent with the SERIAL
type in PostgreSQL?
