I took the liberty to change that to \encoding <x> sets the encoding and \encoding without arguments shows it. Also you can do \echo :ENCODING. That fits in better with the rest. I have a question for you, though. Right now, when I have a non-multibyte backend and a multibyte psql I get this when I start up psql: psql: ERROR: MultiByte support must be enabled to use this function That means I can't use psql on non-multibyte servers in that case. (Probably true for other libpq applications, too.) I don't think that's acceptable. Is there anything you can do there, such as the backend ignoring whatever function is being called? I believe you are going a little too far with ifdef'ing out MULTIBYTE. For instance, it should be perfectly fine to call pg_char_to_encoding, even if there's no possibility of using the encoding. Even when I don't configure for multibyte support I should be able to use all (or at least most) of the functions and get SQL_ASCII or 0 or some such back. I will be interested to work with you and Thomas (and who knows else) on the national character and related issues for the next release. Some of this stuff needs a serious look. -- Peter Eisentraut Sernanders väg 10:115 peter_e@gmx.net 75262 Uppsala http://yi.org/peter-e/ Sweden
