Hi,
In 9.2dev and 9.1, when walreceiver detects an error while sending data to
WAL stream, it always emits ERROR even if there are data available in the
receive buffer. This might lead to loss of transactions because such
remaining data are not received by walreceiver :(
To prevent transaction loss, I'm thinking to change walreceiver so that it
always ignores an error (specifically, emits COMMERROR instead of ERROR)
during sending data. Then walreceiver receives data if available. If an error
occurrs during receiving data, walreceiver can emit ERROR this time.
Comments? Better ideas?
Regards,
