What about partitioning the table using bar='criteria' and bar!='criteria' as partitioning condition?
You can then decide to dump only the first subtable, the second or all the data with pg_dump.
I have similar issues and this is the solution I am working on (still not done).

you are aware you can dump a table at a time, right? pg_dump -t foo
dumps table foo. A partial dumping scheme would probably involve
using pg_dump with various flag in combination with a script that
makes a list of things to dump.
