I.e that if you have to debug a production system, you cannot just look
into the temptables to to pin-point where data is not the way expected.
You have to recreate every intermediary result.
Does that issue not also exist with persistent tables, where the data
you are looking in the debugging stage maybe not be what was present at
the error stage?

Hi
Giving my two dimes. I apologise if some else has given it already.
And it is quite an operations point of view and mostly based on
Oracle. To the best of my knowledge, it applies to Postgres even more.
The data of DB temp tables are not visible outside of the session
that has put it in. In the case of trying to find the problem of code
of functions storing intermediary results, they are just not visible
for the investigator such that one has to do all the steps manually
to detect the point where things go wrong. In my opinion a real pita.
I am not quite following the above.
Do you mean:
1) Not having access to the function code ?
2) Having access to function code, but not the source of data?
Cheers
