7a2fe85b03 Add some notes about why it's not a bug that RI_FKey_check calls
HeapTupleSatisfiesItself without doing LockBuffer first.  This code
is a bit fragile, but AFAICS it's not actually broken.

e06fda0a8b Add a function GetLockConflicts() to lock.c to report xacts holding
locks that would conflict with a specified lock request, without
actually trying to get that lock.  Use this instead of the former ad hoc
method of doing the first wait step in CREATE INDEX CONCURRENTLY.
Fixes problem with undetected deadlock and in many cases will allow the
index creation to proceed sooner than it otherwise could've.  Per
discussion with Greg Stark.

ca1fd0ea5b Move xact.c's partial support for Lists of TransactionIds into pg_list.h.
Needed because lock.c is now going to use the same type of list.

08ae5edc5c Optimize the case where a btree indexscan has current and mark positions
on the same index page; we can avoid data copying as well as buffer refcount
manipulations in this common case.  Makes for a small but noticeable
improvement in mergejoin speed.

35af5422f6 Make the server track an 'XID epoch', that is, maintain higher-order bits
of the transaction ID counter.  Nothing is done with the epoch except to
store it in checkpoint records, but this provides a foundation with which
add-on code can pretend that XIDs never wrap around.  This is a severely
trimmed and rewritten version of the xxid patch submitted by Marko Kreen.
Per discussion, the epoch counter seems the only part of xxid that really
needs to be in the core server.

2b2a50722c Fix all known problems with pg_dump's handling of serial sequences
by abandoning the idea that it should say SERIAL in the dump.  Instead,
dump serial sequences and column defaults just like regular ones.
Add a new backend command ALTER SEQUENCE OWNED BY to let pg_dump recreate
the sequence-to-column dependency that was formerly created "behind the
scenes" by SERIAL.  This restores SERIAL to being truly "just a macro"
consisting of component operations that can be stated explicitly in SQL.
Furthermore, the new command allows sequence ownership to be reassigned,
so that old mistakes can be cleaned up.

Also, downgrade the OWNED-BY dependency from INTERNAL to AUTO, since there
is no longer any very compelling argument why the sequence couldn't be
dropped while keeping the column.  (This forces initdb, to be sure the
right kinds of dependencies are in there.)

Along the way, add checks to prevent ALTER OWNER or SET SCHEMA on an
owned sequence; you can now only do this indirectly by changing the
owning table's owner or schema.  This is an oversight in previous
releases, but probably not worth back-patching.

df18c51f29 Fix DROP OWNED BY to correctly consider the implicitly-deleted objects list for
each object to be deleted, instead of the previous hack that just skipped
INTERNAL dependencies, which didn't really work.  Per report from Tom Lane.

To do this, introduce a new performMultipleDeletions entry point in
dependency.c to delete multiple objects at once.  The dependency code then has
the responsability of tracking INTERNAL and AUTO dependencies as needed.

Along the way, change ObjectAddresses so that we can allocate an ObjectAddress
list from outside dependency.c and not have to export the internal
representation.

fb9e56eea1 Suppress subquery pullup/pushdown when a subquery contains volatile
functions in its targetlist, to avoid introducing multiple evaluations
of volatile functions that textually appear only once.  This is a
slightly tighter version of Jaime Casanova's recent patch.

9bf760f7de Add a 'waiting' column to pg_stat_activity to carry the same information
that ps_status provides by appending 'waiting' to the PS display.  This
completes the project of making it feasible to turn off process title
updates and instead rely on pg_stat_activity.  Per my suggestion a few
weeks ago.
