Can you CONFIRM the 8KB buffer for postgres version 4.1 ??

The reason I suspect postgres is because I have another copy of my

which works like a piece of cake .. for all my various sized input
strings, .. 
however the monitor will APPEND only strings of size <100 , and
starts giving trouble in susequent (not the long stringed append!) appends
and .. once the backend does "not respond", then monitor hangs, ..

Even on exiting from monitor with a ^C and restarting up monitor
(even tried killing postmaster & restarting it), and running
ANY other command (on that particular data base) will cause monitor
to hang ..

help!
