Arrange for VACUUM to delete the init file that relcache.c uses

to save a little bit of backend startup time. This way, the first
backend started after a VACUUM will rebuild the init file with up-to-date

It looks like the multibyte regress tests only work if both
...
the database encoding and the client encoding match the encoding expected
by the test. So, force both of them to be set from the MULTIBYTE
environment var. This allows regress tests to be run successfully in
multibyte environments other than the compiled-in default.
