Improve documentation, too.

Remove timestamps from messages where this would be redundant with the
log_timestamp option.

rather than just being aliases for int4in/int4out.  Give type Oid a
full set of comparison operators that do proper unsigned comparison,
instead of reusing the int4 comparators.  Since pg_dump is now doing
unsigned comparisons of OIDs, it is now *necessary* that we play by
the rules here.  In fact, given that btoidcmp() has been doing unsigned
comparison for quite some time, it seems likely that we have index-
corruption problems in 7.0 and before once the Oid counter goes past
2G.  Fixing these operators is a necessary step before we can think
about 8-byte Oid, too.

(should fix OID bootstraping).

new separate relkind for views (per some discussion back in September).
I didn't force initdb, but rules regress test will show differences
until you do one.

per bug report from Don Baccus.

in pghackers list.  Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention.  pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'.  A newstyle function must be identified
by an associated info routine.  See src/backend/utils/fmgr/README.

function to be present for new-style functions).  Also update some other
out-of-date commentary.
