I can attest that all of 8.3's performance improvements as well all of
the really useful new functions like the one mentioned here make it
well worth the effort to upgrade. I haven't been as excited

I'm trying to declare a variable in PostgreSQL, so I can save some values in
it. After, I want to calculate with this variable.

For the raw command-line SQL, variables, constants, and other procedural
language elements are not appropriate. This is best done in procedures,

like so:
Price|Sum
5|5
4|9
10|19
2|21
7|28
I think what you mean is called running sum, I had the same problem
before, and I found no other solution than creating a column for it,
and calculating its
