If bytea will work for you, it's definitely the thing to use. The only
real drawback to bytea is that there's currently no API to read and
write bytea values in a streaming fashion. If your objects are small
enough that you can load and store them as units, bytea is fine.
BLOBs, on the other hand, have a number of drawbacks --- hard to dump,
impossible to secure, etc.
