Unfortunately there are encoding problems on my machine. I'm getting this output:

Testing with encoding UTF-8:
PQfname(pResult, 4) returned incorrect field name.
PQfname(pResult, 5) returned incorrect field name.
PQfname(pResult, 6) returned incorrect field name.

Testing with encoding SJIS:
Query failed with error:
ERROR:  invalid byte sequence for encoding "UTF8": 0xe59eff
HINT:  This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding".

Instead of a Japanese OS, I used an English (UK) OS and set the system locale to Japanese, but that should be good enough I think.
I also used a new install of PostgreSQL, with only the PostGIS module added.

Okay, I find it difficult to imagine that a bug like this would not have been found before. But if it works fine on your machines, why doesn't it work on my machine?
