Re: Dumping part (not all) of the data in a database...methods?

What about partitioning the table using bar='criteria' and bar!='criteria'

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).
