> In my environment(pgpool 3.1.1 on RHEL4 with two backend PostgreSQL
> 8.1.14 and 7.3.14), I noticed frontend reports following message, when
> backend pg_hba.conf rejects a connection and sends v3 formatted
> ErrorResponce.
> 
> [frontend message]
> $ psql -p 9999 -d test
> psql: server closed the connection unexpectedly
>          This probably means the server terminated abnormally
>          before or while processing the request.
> 
> [backend log]
> $ tail -f /usr/local/pgsql/data/pg_log/postgresql-2006-08-26_194414.log
> ...
> FATAL:  no pg_hba.conf entry for host "131.248.226.93", user "postgres",
> database "test", SSL off
> 
> 
> To forward v3 formatted ErrorResponce, I added two small functions.
> Please find my attachment. The idea for themodification is from
> libpq/fe-connect.c in PostgreSQL 8.1.4. I believe this change helps
