You need to increase the

postmaster's

limit on how many
concurrent backend processes it can start.

In PostgreSQL 6.5 and up, the default limit is 32 processes. You
can increase it by restarting the
<I>
postmaster
</I>
with a suitable
<I>
-N
</I>
value. With the default configuration you can set
<I>
-N
</I>
as large as 1024. If you need more, increase
<SMALL>
MAXBACKENDS
</SMALL>
in
<I>
include/pg_config.h
</I>
and rebuild.
You can set the default value of
<I>
-N
</I>
at configuration time,
if you like, using

<I>
--with-maxbackends

switch.
