That's just bogus syntax. The function body has to be surrounded by
single quotes ' not double quotes ". (Also, any single quote in the
function body has to be written as '' or \' to get past the string-
literal parser. Kind of a pain --- you might want to use something
like pgaccess to make editing easier.)
