Well, I'm saying 'zombie' not like *nix terminology. I'm talking about
server proces that are waiting for a client that die unexpectly and can't
close connection.

No, no sorry, Postgres is HARDER a lot, we have more than 70 simultaneos
connection over ODBC, 107 tables, millions of rows and nothing has happened
since april,  really good job ! Update the database is in our TODO LIST but
we try to wait for a version with native replication (We have heard that is
possible to be available in 7.4.X ) . We have still a lot of work and there
is a problem with time representation that has changed between 7.1.X to
7.2.X that we can't resolve (decimal fraction of time) and we have a lot of
server side code. Thanks!
