Here's an updated version of the stripped-down patch, now with
documentation changes, plus a couple of minor bug fixes.
Another update, marching towards committing. Now with pg_dump/pg_dumpall
support, and collation/ctype is also shown in psql \l output.
I wonder if we should provide a shorthand "LOCALE=<localename>" option,
in addition to separate COLLATE and CTYPE options? Most people will
always set them together. It could also set the rest of the locale
categories, lc_numeric, lc_monetary, and so on, as database-specific
options. Like "ALTER DATABASE <dbname> SET lc_messages=<localename> ..."
would.
