If you need to work with it in memory, you're better off using the bytea (same
thing as a varbinary).  LOBs are generally for when the data is so large that
the performance of your application would be comprimised if you allocated
memory for the contents.  LOBs allow you to do streaming so that you don't
need to allocate memory.  Only the lo_export/lo_import functions require a
file.  All of the other LOB functions only require a stream that's chunked
into byte arrays.
