If you start from the perspective that stored procedures are in many
respects more like psql scripts than functions, this shouldn't be
too surprising. If you have a psql script with multiple database
transactions, you know that other processes can change things
between transactions. Same deal with SPs.
The whole raison d'être for SPs is that there are cases where people
need something *different* from functions. While it would be *nice*
to leverage plpgsql syntax for a stored procedure language, if it
means we have to behave like a function, it's not worth it.
