If we're bringing up odd encoding issues, why not talk about the mystery
encoding of the shared catalogs? :)
Basically depending on which database you're logged into when you alter
a catalog will affect what encoding the new object appears as in the
shared catalog.
This for one makes it impossible for us in phpPgAdmin to display a list
of databases, where some database names are in EUC and some are in UTF-8
and some are in LATIN5...
I bring it up as I notice that in MySQL 5 at least, all system object
names (in our case that'd be all strings in the shared catalogs) are
stored in UTF-8, always.
