Kind of hard to believe ... is there any sign of distress in the

It's striking that this log shows a server ack of the INSERT, but no server
ack of the COMMIT. Maybe that's just an oversight in the ESQL/C logging
logic, but I wonder what's actually getting to the server. You might try
enabling log_statement = all so you can get a trace of what the server
thinks is happening.
