So - the error is that occasionally, some values aren't entered in the raw
table nor summarised in the daily table?
Does your live insertion code check the result-code from PG? If the insert is
failing, it should say so.
I'd suspect some concurrency issues, but I can't see anything obvious. Testing
for this is a pain, but it produces exactly these kind of problems. Try
running 5 test processes at once, all inserting simultaneously and see if
that reproduces your problem.
If no-one else has a bright idea, I'll try running it with some test data on
my end this afternoon (London time) if I get a chance.
