Hmmm. Probably I'm biased towards my compiler with an integer linear
flavor field, where C-like "%" is always a pain, however you look at it.
I'm not sure of physical inventories with negative numbers though. In
accounting, I thought that a negative number was a positive number with
"debit" written above. In finance, no problem to get big deficits:-)
Now about the use case, I'm not sure that you would like to write your
financial and physical inventory stuff within a pgbench test script,
whereas in such a script I do expect when doing a modulo with the size of
a table to have a positive result so that I can expect to find a tuple
there, hence the desired "positive remainder" property for negative
dividends.
