I saw the same behavior with Functions and Procedures. At first, I could not tell what made one go into the Function folder and one go into the Procedure one. The one thing that clearly distinguishes a Procedure (to be placed into the Procedures folder in PgAdminIII) is if you include an OUT parameter. The first time I wrote a Function with an OUT parameter, I could not find it in the functions folder. I thought at first that it didn't compile. Then I noticed it in the Procedures folder. Probably a lot of other characteristics that make it different, but that is at least one. :)

Merlin,
thank you for clarifying this. So, given your hint, I didn't miss SP
until now, but this will probably change in future. ;-)
