rows in relation, so that code still works for > LONG_MAX rows in rel.

Then, run a small reality test with $ANT to see whether it works.

constraint.  This case (a) is useless, (b) violates SQL92, and
(c) is certain to cause a failure downstream when we try to create
an index with duplicated column names.  So give an appropriate error
message instead of letting the index failure occur.  Per report from
Colin Strickland.  NOTE: currently, CREATE INDEX fooi ON foo(f1,f1)
still fails with 'cannot insert duplicate key' error.  Should we
change that too?  What about functional indexes?

the setTimestamp method is called.  Thanks to Dave Harkness for this
suggestion.

to start it before we have acquired the data directory lock; also a
bad idea to start it before we have set up to catch SIGCHLD signals.

useful as yet, since its primary source of information is (full) VACUUM,
which makes a concerted effort to get rid of free space before telling
the map about it ... next stop is concurrent VACUUM ...

Probably the right fix is to remove 'current' special value entirely,
but I don't want to see regression test failures until that happens.

actually work.  It had been throwing an Assert as of my recent changes
to bufmgr.c, but was not really right even before that AFAICT.

immediately, we will fork a child even if the database state does not
permit connections to be accepted (eg, we are in recovery mode).
The child process will correctly reject the connection and exit as
soon as it's finished collecting the connection request message.
However, this means that reaper() must be prepared to see child
process exit signals even while it's waiting for startup or shutdown
process to finish.  As was, a connection request arriving during a
database recovery or shutdown would cause postmaster abort.

appropriate, e.g., with outer joins.

Add 'do { ... } while (0)' decoration to eliminate compiler warnings.

deadlock in concurrent heap_updates: allow RelationGetBufferForTuple to
select any page of the rel, and put the onus on it to lock both buffers

API of ReleaseAndReadBuffer.

have any newly-dead tuples on them.  This is a longstanding deficiency
that prevents VACUUM from compacting a file as much as one would expect.
Change requires fixing repair_frag to not assume that fraged_pages is
a subset of vacuum_pages.
Also make some further cleanups of places that assumed page numbers fit
in int and tuple counts fit in uint32.

system is tremendously short of buffers ... but a bug is a bug.

do anything yet, but it has the necessary connections to initialization
and so forth.  Make some gestures towards allowing number of blocks in
a relation to be BlockNumber, ie, unsigned int, rather than signed int.
(I doubt I got all the places that are sloppy about it, yet.)  On the
way, replace the hardwired NLOCKS_PER_XACT fudge factor with a GUC
variable.
