Per recent discussion, add_missing_from has been deprecated for long enough to
consider removing, and it's getting in the way of planned parser refactoring.
The system now always behaves as though add_missing_from were OFF.

Itagaki Takahiro with some changes from me

pam_message array contains exactly one PAM_PROMPT_ECHO_OFF message.
Instead, deal with however many messages there are, and don't throw error
for PAM_ERROR_MSG and PAM_TEXT_INFO messages.  This logic is borrowed from
openssh 5.2p1, which hopefully has seen more real-world PAM usage than we
have.  Per bug #5121 from Ryan Douglas, which turned out to be caused by
the conv_proc being called with zero messages.  Apparently that is normal
behavior given the combination of Linux pam_krb5 with MS Active Directory
as the domain controller.

Patch all the way back, since this code has been essentially untouched
since 7.4.  (Surprising we've not heard complaints before.)

Note: the schema of pg_trigger has not actually changed; we've just started
to use a column that was there all along.  catversion bumped anyway so that
this commit is included in the history of potentially interesting changes
to system catalog contents.

ASCII-art style of table output to be upgraded to use Unicode box drawing
characters if desired.  By default, psql will use the Unicode characters
whenever client_encoding is UTF8.

The patch forces linestyle=ascii in pg_regress usage, ensuring we don't
break the regression tests in Unicode locales.

Bogus coding appears to be new in 8.4 --- older releases had a much

execMain.c and into a new plan node type LockRows.  Like the recent change
to put table updating into a ModifyTable plan node, this increases planning
flexibility by allowing the operations to occur below the top level of the
plan tree.  It's necessary in any case to restore the previous behavior of
having FOR UPDATE locking occur before ModifyTable does.

This partially refactors EvalPlanQual to allow multiple rows-under-test
to be inserted into the EPQ machinery before starting an EPQ test query.
That isn't sufficient to fix EPQ's general bogosity in the face of plans
that return multiple rows per test row, though.  Since this patch is
mostly about getting some plan node infrastructure in place and not about
fixing ten-year-old bugs, I will leave EPQ improvements for another day.

Another behavioral change that we could now think about is doing FOR UPDATE
before LIMIT, but that too seems like it should be treated as a followon
patch.

* Stop escaping ? and {.  As of SQL:2008, SIMILAR TO is defined to have
POSIX-compatible interpretation of ? as well as {m,n} and related constructs,
so we should allow these things through to our regex engine.

* Escape ^ and $.  It appears that our regex engine will treat ^^ at the
beginning of the string the same as ^, and similarly for $$ at the end of
the string, which meant that SIMILAR TO was effectively ignoring ^ at the
start of the pattern and $ at the end.  Since these are not supposed to be
metacharacters, this is a bug.

The second part of this is arguably a back-patchable bug fix, but I'm
hesitant to do that because it might break applications that are expecting
something like "col SIMILAR TO '^foo$'" to work like a POSIX pattern.
Seems safer to only change it at a major version boundary.

Per discussion of an example from Doug Gorley.

They are now handled by a new plan node type called ModifyTable, which is
placed at the top of the plan tree.  In itself this change doesn't do much,
except perhaps make the handling of RETURNING lists and inherited UPDATEs a
tad less klugy.  But it is necessary preparation for the intended extension of
allowing RETURNING queries inside WITH.

Add a variant of pg_get_triggerdef with a second argument "pretty" that
causes the output to be formatted in the way pg_dump used to do.  Use this
variant in pg_dump with server versions >= 8.5.

This insulates pg_dump from most future trigger feature additions, such as
the upcoming column triggers patch.

friends).  This code has all been ifdef'd out for many years, and doesn't
seem to have any prospect of becoming any more useful in the future.
EXPLAIN ANALYZE is what people use in practice, and I think if we did want
process-wide counters we'd be more likely to put in dtrace events for that
than try to resurrect this code.  Get rid of it so as to have one less detail
to worry about while refactoring execMain.c.

I also thank Bernd Helmle for the documentation help on the previous settings
patch, which I forgot on the commit message.

Create a new catalog pg_db_role_setting where they are now stored, and better
encapsulate the code that deals with settings into its realm.  The old
datconfig and rolconfig columns are removed.

psql has gained a \drds command to display the settings.

Backwards compatibility warning: while the backwards-compatible system views
still have the config columns, they no longer completely represent the
configuration for a user or database.

Catalog version bumped.

Partially revert the previous patch I installed and replace it with a more
general fix: any time a snapshot is pushed as Active, we need to ensure that it
will not be modified in the future.  This means that if the same snapshot is
used as CurrentSnapshot, it needs to be copied separately.  This affects
serializable transactions only, because CurrentSnapshot has already been copied
by RegisterSnapshot and so PushActiveSnapshot does not think it needs another
copy.  However, CommandCounterIncrement would modify CurrentSnapshot, whereas
ActiveSnapshots must not have their command counters incremented.

I say "partially" because the regression test I added for the previous bug
has been kept.

(This restores 8.3 behavior, because before snapmgr.c existed, any snapshot set
as Active was copied.)

Most things should be cleaned by "make clean", except the parts that are
shipped in the tarball.  These rules had gotten a bit out of whack after
the various restructurings of the documentation build rules.

inheritance parent tables are compared using equal(), instead of doing
strcmp() on the nodeToString representation.  The old implementation was
always a tad cheesy, and it finally fails completely as of 8.4, now that the
node tree might contain syntax location information.  equal() knows it's
supposed to ignore those fields, but strcmp() hardly can.  Per recent
report from Scott Ribe.

(Or rather, unbreak what the previous commit broke)
