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.
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.
Fixed a few trivial memory leaks reported by Coverity just to test my setup.

Add server support for "plugin" libraries that can be used for add-on tasks
such as debugging and performance measurement. This consists of two features:
a table of "rendezvous variables" that allows separately-loaded shared
libraries to communicate, and a new GUC setting "local_preload_libraries"
that allows libraries to be loaded into specific sessions without explicit
cooperation from the client application. To make local_preload_libraries
as flexible as possible, we do not restrict its use to superusers; instead,
it is restricted to load only libraries stored in $libdir/plugins/. The
existing LOAD command has also been modified to allow non-superusers to
LOAD libraries stored in this directory.
This patch also renames the existing GUC variable preload_libraries to
shared_preload_libraries (after a suggestion by Simon Riggs) and does some
code refactoring in dfmgr.c to improve clarity.

Get rid of "lookahead" functionality in plpgsql's yylex() function,
and instead make the grammar production for the RETURN statement do the
heavy lifting. The lookahead idea was copied from the main parser, but
it does not work in plpgsql's parser because here gram.y looks explicitly
at the scanner's yytext variable, which will be out of sync after a
failed lookahead step. A minimal example is
create or replace function foo() returns void language plpgsql as '
begin
perform return foo bar;
end';
which can be seen by testing to deliver "foo foo bar" to the main parser
instead of the expected "return foo bar". This isn't a huge bug since
RETURN is not found in the main grammar, but it could bite someone who
tried to use "return" as an identifier.

Refactor GUC set_config_option function:
The main reason for refactoring was that set_config_option() was too
overloaded function and its behavior did not consistent. Old version of
set_config_function hides some messages. For example if you type:
tcp_port = 5432.1
then old implementation ignore this error without any message to log
file in the signal context (configuration reload). Main problem was that
semantic analysis of postgresql.conf is not perform in the
ProcessConfigFile function, but in the set_config_options *after*
context check. This skipped check for variables with PG_POSTMASTER
context. There was request from Joachim Wieland to add more messages
