iinvalid string enlargement PG 7.4.5
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi all,
this morning I perform an upgrade 7.4.2 -> 7.4.5 and
after 6 months without errors this night a backend
crashed:
ERROR: invalid string enlargement request size 1476395004
DEBUG: AbortCurrentTransaction
WARNING: AbortTransaction and not in in-progress state
ERROR: could not send data to client: Broken pipe
PANIC: error during error recovery, giving up
DEBUG: child process (PID 32247) was terminated by signal 6
LOG: server process (PID 32247) was terminated by signal 6
LOG: terminating any other active server processes
do you have any idea on what could be the reason ?
Regards
Gaetano Mendola

I'm betting on a communications failure. What I see there is a few
bytes of corrupted data received from the client (ie, a ridiculous
message-length word) followed by abrupt disconnect *by the client*.
You have any logs indicating what might have happened at the client
end?

On the client side I have always:

I searched the error "invalid string enlargment request" in the logs of last week and I never encountered it.
Only since today after the 7.4.5 installation. Note that the request size is always the same!
