Hello all - I apologize for the newbie-esque question, but the debug output
from postgres when you have a bug in your PL/pgSQL procedure is none to
detailed.

I've created the following procedure and am getting an error when I try to
update the table. The error is something like "parse error near ; on line 50".
Line 50 is the last line.

There's probably something glaring wrong in here that I'm not seeing, but any
help would be appreciated.

I don't know if the \ at the end of the line is a problem, but those were
added late in the game and didn't change the error message ;-)
