about partitioning

Hello all,

my application is coming to a point on which 'partitioning' seems to be
the solution for many problems:

- query speed up
- data elimination speed up



I'dd like to get the feeling of it by talking to people who use
partitioning, in general..

- good, bad,
- hard to manage, easy to manage,
- processing over-head during INSERT/UPDATE,
- stability/compatibility of pg_dump and restore operations,
- how many partitions would be reasonable for read _and_ write  access
optimal speed;

thx
