OK, I am still just throwing out ideas. I am not sure we even have
enough people who want statement_timestamp to put it in TODO. I do think
we have a standards issue.
My personal opinion is that most people think current_timestamp and
now() are statement start time, not transaction start time. In the past
we have told them the standard requires that but now I think we are not
even sure if that is correct.
So, I have these concerns:
our CURRENT_TIMESTAMP may not be standards complianteven if it is, it is probably not returning the value most people
wantmostpeople don't know it is returning the transaction start time
So, we can just throw the TODO item you mentioned above with a question
mark, or we can try to figure out what to return for CURRENT_TIMESTAMP,
now(), and perhaps create a TRANSACTION_TIMESTAMP.
So, do people want to discuss it or should we just throw it in TODO with
a question mark?
