Not really ... have they actually advanced? :)
My main problem with them is that you can't use text output from pg_dump, only one of the binary options, and if pg_dump hoses something that means you can't go in and hand-edit it to the point where you can reload the dump.
That scares me ... I've never lost data due to PG_DUMP messing up but being able to hack the text output gives me a comfortable feeling.
Also the LOB API is really clunky, IIRC they're not VACUUMed etc.
