Hi Peter,

Thanks for the tip.  The locale we're using is en_US.UTF-8.  From my limited
knowledge of locales, that's a non-C one isn't it?

Am I right in saying that to fix it I need to initdb again with a C locale?
How do I go about doing that on an environment with some 132 databases?

What a pain!

Chris
