It doesn't really address the question of how you know which one to use at any particular line of code; or even more to the point, what mechanism will warn you if you use the wrong one. My gut feeling about this is that we could probably enforce such a distinction if we were using C++, but while coding in C I have no confidence in it. (And no, that's not a vote to move to C++ ...) regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
