Thanks Tom, using initdb to create a new data directory (cluster?) worked, using "English_United..." rather than en_GB as you suggested.

I've never had to do that before - always just used the default Postgres installation and selected "English United Kingdom" during the install. That didn't seem to work on this server - it insisted on being United States. Anyway, learning how to use the command line is no bad thing.

Thanks for your help.
