Обсуждение: now() more precise than the transaction
I know this was discussed a while back, and I just reviewed the discussion. It
looks like the proposal was to make now('immediate') get the exact current
time.
But is there a way to get that now? I can't find anything in the FAQs or in
the 7.3 docs that indicates any of the functions do anything other than
now('transaction').

Try CURRENT_TIMESTAMP
You should be able to get your time that way

I think he wants timeofday. CURRENT_TIMESTAMP should be the same as
now('transaction'), which I think he said wasn't what he wanted.

The documentation explicitly says now() is just an alias for
current_timestamp. I don't know that it's right but I assume so.

timeofday appears to return text though. Do I just assume it will always cast
cleanly to a timestamp? It doesn't seem to be in the same format as timestamps
print though.

Btw, no need to quote back the whole original message, I keep outgoing
messages.

But it does come out in a format that the timestamp input can accept.
It shouldn't be a problem to cast it to timestamp.
