Hi,

+          With <literal>load-balancing</literal> policy postmaster choose
proxy with lowest load average.
+          Load average of proxy is estimated by number of clients
connection assigned to this proxy with extra weight for SSL connections.

I think 'load-balanced' may be better than 'load-balancing'.
postmaster choose proxy -> postmaster chooses proxy

+          Load average of proxy is estimated by number of clients
connection assigned to this proxy with extra weight for SSL connections.

I wonder if there would be a mixture of connections with and without SSL.

+         Terminate an idle connection pool worker after the specified
number of milliseconds.

Should the time unit be seconds ? It seems a worker would exist for at
least a second.

It would be better to update the year in the header.

+        * Use then for launching pooler worker backends and report error

Not sure I understand the above sentence. Did you mean 'them' instead of
'then' ?

Cheers
