Thread: proxying connections

Hi,

I am trying to develop a proxy for postgresql that
will distribute the load between multiple postgresql
database servers and have so far failed to even get a
connection.

What I am trying to do is to create a TCP socket
server and a client and forward all requests coming
into the server through the client and vice versa.

So far, it has not worked at all.

Can anybody shed any light on this or a better way of
doing this.

Thanks and best wishes,


Mork

Did you take a look at sqlrelay or pgpool ?

In the past I wrote a similar thing in C to forward TCP requests.
I think you have to use either fork() or threads in order to keep on
listening on connection while you serve others. I used fork() at the time
but I would use threads nowadays. Anyway, after I saw the rising of all
these replication mechanism I wonder if such utility would be still
necessary.
