I have developed the following patch against CVS. Tatsuo, you can use
it as a starting point. It adds a comment to encnames.c and reorders
utf8_and_iso8859.c to match the existing order. I also added the
missing entries at the bottom. I checked for pg_conv_map in the source
code and only utf8_and_iso8859.c has that structure, so I assume it is
the only one that also depends on the encnames.c ordering.

Looking at 8.0.X, it has the matching order, so we are OK there, but it
doesn't have the trailing entries. Tatsuo, are those needed?
