postgresql/connect.cpp accidentally uses the <:: trigraph in the typedefs at the top of the file. You need a space before the template args to avoid that.

I think you mean the "<:" digraph. It represents the "[" (opening square bracket) character. The official term is "alternative token" (see section 2.5 of the standard), because some of the tokens have more than two characters. (These include the bitwise and Boolean word operators, i.e. "and".) They're considered after the preprocessor (phase 3 of section 2.1), and trigraphs are done earlier than that (in phase 1). -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
