Re-connecting dropped connections

Hi,

I'm the author of the Smalltalk PostgreSQL library ( 
http://sourceforge.net/projects/st-postgresql/).  This library uses the 
socket level frontend/backend protocol and allows Smaltalk programers to 
build PostgreSQL apps.

Here is a question from someone who uses the library.  It boils down to: 
Is there any way to re-connect to an existing session if the connection 
briefly drops?

The question I received ...
______________________

I've been having, more or less forever, problems with connecting to 
postgres. Half-way through publishing things just die. I'm pretty sure 
this is my isp's fault, because I know that my connection just drops for 
intervals ranging from very short to quite lengthy. e.g. I get kicked of 
IRC, and depending how long the disconnect is, I may or may not be able 
to automatically reconnect. If it's too long, it decides I spelled the 
host name wrong because it can't get to the dns servers and gives up. I 
think that shorter versions of this are killing my postgres connects 
(this shows up in VW as a ECONNREST error). I also think it's my ISP 
because it happens to both my Linux box and my Windows machine.

However, it doesn't affect Oracle connections. This makes me wonder if 
there's something that could be done to make the postgres connections 
more robust and able to re-establish the connection if it goes away 
briefly. Obviously if it goes away badly enough that my transaction 
state is lost I'm out of luck, but I wonder if there's somewhere in the 
middle that there's room to work.
