Sending a couple hundred K to the whole list probably wasn't the thing
to do (but maybe Marc will reject the posting and save other people the
load on their mailboxes).
Anyway, I can't see any sign here that the backend thinks anything is
wrong, up till the time it gets bogus input from the client. I assume
the queries shown in the log correspond to what you expect the client
application to be issuing?
I think that you need to look to the client side to figure out the
problem. Since you said you were using PHP scripts on a webserver,
my best guess is that you are having troubles with reusing a shared
connection to a backend --- that is, multiple scripts are interfering
with each other and causing fragmentary commands to be sent down the
connection.
I don't know anything about PHP myself, but you can find discussions
about this in the Postgres mail list archives. I recall seeing
something about it just a day or two ago (unfortunately I forget which
list).
I have a very vague recollection that trying to share a connection with
'pconnect' doesn't work reliably except in the latest PHP releases.
Better dig around and check that before you believe it, however.
