Dear list,
As discussed extensively in the past [1], pg_dump tends to be slow for
tables that contain bytea columns with large contents. Starting with
postgres version 8.5 the COPY format of bytea was changed from escape to
hex [1], giving ~50% performance boost.
However, we experience heavy

Your application is simply broken if it assumes that DISTINCT results in
ordering the rows. The only thing that guarantees that is an ORDER BY.

Scott,
It seems that each of the server postmaster.exe processes takes up
approx. 5 MB of server memory (the virtual memory size column in task
manager), and I guess this truly is the private memory these processes
require. This number is roughly the same for 8.4 and 9.0 .

there anything I can do to optimize?
That sounds about the right ballpark for a working backend process with
caches loaded up. If that's too much for you, you ought to be using
