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.

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.

e8ea9e9587 Implement archive_timeout feature to force xlog file switches to occur no more
than N seconds apart.  This allows a simple, if not very high performance,
means of guaranteeing that a PITR archive is no more than N seconds behind
real time.  Also make pg_current_xlog_location return the WAL Write pointer,
add pg_current_xlog_insert_location to return the Insert pointer, and fix
pg_xlogfile_name_offset to return its results as a two-element record instead
of a smashed-together string, as per recent discussion.

bb764e94ce Produce a clean failure in configure when dtrace is selected but cannot be
found.  Besides stopping those early who have no dtrace installed
whatsoever, this will also alert those who have dtrace in /usr/sbin, which
might not be in the path, which would produce confusing failures much later
in the build process.

Add documentation about pointing configure to find dtrace.

abc3120e9b 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.

Korry Douglas, with a little help from Tom Lane.

3f8db37c2f Tweak SPI_cursor_open to allow INSERT/UPDATE/DELETE RETURNING; this was
merely a matter of fixing the error check, since the underlying Portal
infrastructure already handles it.  This in turn allows these statements
to be used in some existing plpgsql and plperl contexts, such as a
plpgsql FOR loop.  Also, do some marginal code cleanup in places that
were being sloppy about distinguishing SELECT from SELECT INTO.

b09bfcaa57 Add a feature for automatic initialization and finalization of dynamically
loaded libraries: call functions _PG_init() and _PG_fini() if the library
defines such symbols.  Hence we no longer need to specify an initialization
function in preload_libraries: we can assume that the library used the
_PG_init() convention, instead.  This removes one source of pilot error
in use of preloaded libraries.  Original patch by Ralf Engelschall,
preload_libraries changes by me.

7946f77220 Cause ALTER TABLE to perform ALTER COLUMN DROP DEFAULT operations during
the DROP pass rather than the ADD_CONSTR pass.  On examining the code I
think this was just an oversight rather than intentional, and it seems
to satisfy the principle of least surprise better than the alternative
solution that was discussed.  Add an example to the ref page showing how
to do ALTER TYPE and update the default in one command.  Per gripe from
Markus Bertheau that that wasn't possible.
