Thanks for the response. PostgreSQL is already configured to have twice 
as many connections as Apache has children, assuming that i'm 
understanding the configuration correctly. This is set in 
postgresql.conf, for instance:
    max_connections = 256

And the section of Apache's httpd.conf that controls processes looks 
like this:
    StartServers       8
    MinSpareServers    5
    MaxSpareServers   20
    ServerLimit      256
    MaxClients       128
    MaxRequestsPerChild  1024
I'm not as certain how ServerLimit affects things, but my understanding 
is that MaxClients is the important number here, as it determines how 
many children Apache can have.

Is there something else i can check in PostgreSQL or Apache? When i 
examine the PostgreSQL logs, i don't see anything out of the ordinary 
(once the "unexpected EOF on client connection" errors are stripped 
out).
