I made it reject all but latin letters, which is the same restriction
that's in place for timezone set filenames.  That might be overly
strong, but we definitely have to forbid "." and "/" (and "\" on
Windows).  Do we want to restrict it to letters, digits, underscore?
Or does it need to be weaker than that?

Um ... I don't see that; I get

regression=# \dF              List of text search configurations  Schema   |    Name    |              Description

Are you sure you're using CVS-head psql?

Yeah, I wanted to discuss that with you.  Code examples in sgml docs are
a bad idea: they're impossible to use as actual templates, because of
all the weird markup changes, and there's no easy way to notice if
they're broken.  It would be better to remove these from the docs and
set them up as contrib modules.
