5d5087363d Replace the BufMgrLock with separate locks on the lookup hashtable and 
the freelist, plus per-buffer spinlocks that protect access to individual
shared buffer headers.  This requires abandoning a global freelist (since
the freelist is a global contention point), which shoots down ARC and 2Q
as well as plain LRU management.  Adopt a clock sweep algorithm instead.
Preliminary results show substantial improvement in multi-backend situations.

f55339577b Adjust OS-specific kernel settings to mention old and new BSD methods of 
adjusting values:

ffef9a9de4 Clarify PGPASSWORD usage: 
! authentication.  Use of this environment variable is not
! recommended for security reasons (some operating systems
! allow non-root users to see process environment variables via
! <application>ps</>); instead consider using  the
! <filename>~/.pgpass</> file (see <xref linkend="libpq-pgpass">).

taken automatically, but this is only true with respect to user tables.

60b2444cc3 Add code to prevent transaction ID wraparound by enforcing a safe limit 
in GetNewTransactionId().  Since the limit value has to be computed
before we run any real transactions, this requires adding code to database
startup to scan pg_database and determine the oldest datfrozenxid.
This can conveniently be combined with the first stage of an attack on
the problem that the 'flat file' copies of pg_shadow and pg_group are
not properly updated during WAL recovery.  The code I've added to
startup resides in a new file src/backend/utils/init/flatfiles.c, and
it is responsible for rewriting the flat files as well as initializing
the XID wraparound limit value.  This will eventually allow us to get
rid of GetRawDatabaseInfo too, but we'll need an initdb so we can add
a trigger to pg_database.
