3b93fba823 Remove plpython casts C source code casts: 
It removes last remaining casts inside struct definitions.
Such usage is bad practice, as it hides problems from compiler.

Reason for the cast is popular practice in some circles
to define functions as foo(MyObj *) instead of foo(PyObject *)
thus avoiding a local variable inside functions and make
direct calling easier.  As pl/python does not use such style,
the casts were unnecessary from the start.

9c9b619473 Remove the CheckpointStartLock in favor of having backends show whether they 
are in their commit critical sections via flags in the ProcArray.  Checkpoint
can watch the ProcArray to determine when it's safe to proceed.  This is
a considerably better solution to the original problem of race conditions
between checkpoint and transaction commit: it speeds up commit, since there's
one less lock to fool with, and it prevents the problem of checkpoint being
delayed indefinitely when there's a constant flow of commits.  Heikki, with
some kibitzing from Tom.

b3005276eb Decouple the values of TOAST_TUPLE_THRESHOLD and TOAST_MAX_CHUNK_SIZE. 
Add the latter to the values checked in pg_control, since it can't be changed
without invalidating toast table content.  This commit in itself shouldn't
change any behavior, but it lays some necessary groundwork for experimentation
with these toast-control numbers.

Note: while TOAST_TUPLE_THRESHOLD can now be changed without initdb, some
thought still needs to be given to needs_toast_table() in toasting.c before
unleashing random changes.

17285959c1 Add URL for: 
* Improve speed with indexes

  For large table adjustments during VACUUM FULL, it is faster to cluster
  or reindex rather than update the index.  Also, index updates can bloat
  the index.

9a527f1848 Fix check_sql_fn_retval to allow the case where a SQL function declared to 
return void ends with a SELECT, if that SELECT has a single result that is
also of type void.  Without this, it's hard to write a void function that
calls another void function.  Per gripe from Peter.

Back-patch as far as 8.0.

8875d0987d Fix oversight in coding of _bt_start_vacuum: we can't assume that the LWLock 
will be released by transaction abort before _bt_end_vacuum gets called.
If either of these "can't happen" errors actually happened, we'd freeze up
trying to acquire an already-held lock.  Latest word is that this does
not explain Martin Pitt's trouble report, but it still looks like a bug.
