o note that now pg_database has a new attribuite "encoding" even

if MULTIBYTE is not enabled. So be sure to run initdb.

o these patches are made against the latest source tree (after
Bruce's massive patch, I think) BTW, I noticed that after running
regression, the oid field of pg_type seems disappeared.

	regression=> select oid from pg_type; ERROR:  attribute
	'oid' not found

this happens after the constraints test. This occures with/without
my patches. strange...

o pg_database_mb.h, pg_class_mb.h, pg_attribute_mb.h are no longer
used, and shoud be removed.

o GetDatabaseInfo() in utils/misc/database.c removed (actually in
#ifdef 0). seems nobody uses.
