Add vacuumdb option --analyze-in-stages which runs ANALYZE three times
with different configuration settings, adopting the logic from the
analyze_new_cluster.sh script that pg_upgrade generates. That way,
users of pg_dump/pg_restore can also use that functionality.
Change pg_upgrade to create the script so that it calls vacuumdb instead
of implementing the logic itself.
This results in spurious empty lines in the server log. Instead, add
the newlines only when printing out the --echo output. In some cases,
this was already done, leading to two newlines being printed. Clean
that up as well.

Several previous commits have added columns to various \d queries without
updating their translate_columns[] arrays, leading to potentially incorrect
translations in NLS-enabled builds. Offenders include commit 893686762
(added prosecdef to \df+), c9ac00e6e (added description to \dc+) and
3b17efdfd (added description to \dC+). Fix those cases back to 9.3 or
9.2 as appropriate.
Since this is evidently more easily missed than one would like, in HEAD
also add an Assert that the supplied array is long enough. This requires
an API change for printQuery(), so it seems inappropriate for back
branches, but presumably all future changes will be tested in HEAD anyway.
In HEAD and 9.3, also clean up a whole lot of sloppiness in the emitted
SQL for \dy (event triggers): lack of translatability due to failing to
pass words-to-be-translated through gettext_noop(), inadequate schema
qualification, and sloppy formatting resulting in unnecessarily ugly
-E output.

Previously, lookups of non-existent user names could return "Success";
it will now return "User does not exist" by resetting errno. This also
centralizes the user name lookup code in libpgport.
Report and analysis by Nicolas Marchildon; patch by me
Previously, -d option for pg_isready was broken. When the name of the
database was specified by -d option, pg_isready failed with an error.
When the conninfo specified by -d option contained the setting of the
host name but not Numeric IP address (i.e., hostaddr), pg_isready
displayed wrong connection message. -d option could not handle a valid
URI prefix at all. This commit fixes these bugs of pg_isready.
Backpatch to 9.3, where pg_isready was introduced.
Per report from Josh Berkus and Robert Haas.
Original patch by Fabrízio de Royes Mello, heavily modified by me.
pg_isready displays the host name and the port number that it uses to connect
to the server. So far, pg_isready didn't use the conninfo specified in -d option
for calculating those host name and port number. This can lead to wrong display
to a user. This commit changes pg_isready so that it uses the conninfo for that
calculation.
Original patch by Phil Sorber, modified by me.
We had two copies of this function in the backend and libpq, which was
already pretty bogus, but it turns out that we need it in some other
programs that don't use libpq (such as pg_test_fsync). So put it where
it probably should have been all along. The signal-mask-initialization
support in src/backend/libpq/pqsignal.c stays where it is, though, since
we only need that in the backend.
libpgcommon is a new static library to allow sharing code among the
various frontend programs and backend; this lets us eliminate duplicate
implementations of common routines. We avoid libpgport, because that's
intended as a place for porting issues; per discussion, it seems better
to keep them separate.
The first use case, and the only implemented by this patch, is pg_malloc
and friends, which many frontend programs were already using.
At the same time, we can use this to provide palloc emulation functions
for the frontend; this way, some palloc-using files in the backend can
also be used by the frontend cleanly. To do this, we change palloc() in
the backend to be a function instead of a macro on top of
MemoryContextAlloc(). This was previously believed to cause loss of
performance, but this implementation has been tweaked by Tom and Andres
so that on modern compilers it provides a slight improvement over the
previous one.
This lets us clean up some places that were already with
localized hacks.
Most of the pg_malloc/palloc changes in this patch were authored by
Andres Freund. Zoltán Böszörményi also independently provided a form of
that. libpgcommon infrastructure was authored by Álvaro.
Without this, building in src/bin/scripts directly will fail if
libpgport wasn't built first. Other bin components are handled the same
way.

On top of the previous support in pg_dump, add support to specify
multiple tables (by using the -t option multiple times) to
pg_restore, clsuterdb, reindexdb and vacuumdb.
Josh Kupershmidt, reviewed by Karl O. Pinc
On some platforms these functions return NULL, rather than the more common
practice of returning a pointer to a zero-sized block of memory. Hack our
various wrapper functions to hide the difference by substituting a size
request of 1. This is probably not so important for the callers, who
should never touch the block anyway if they asked for size 0 --- but it's
important for the wrapper functions themselves, which mistakenly treated
the NULL result as an out-of-memory failure. This broke at least pg_dump
for the case of no user-defined aggregates, as per report from
Matthew Carrington.
Back-patch to 9.2 to fix the pg_dump issue. Given the lack of previous
complaints, it seems likely that there is no live bug in previous releases,
even though some of these functions were in place before that.
We had a number of variants on the theme of "malloc or die", with the
majority named like "pg_malloc", but by no means all. Standardize on the
names pg_malloc, pg_malloc0, pg_realloc, pg_strdup. Get rid of pg_calloc
entirely in favor of using pg_malloc0.
This is an essentially cosmetic change, so no back-patch. (I did find
a couple of places where psql and pg_dump were using plain malloc or
strdup instead of the pg_ versions, but they don't look significant
enough to bother back-patching.)
Before, some places didn't document the short options (-? and -V),
some documented both, some documented nothing, and they were listed in
various orders. Now this is hopefully more consistent and complete.
A number of utility programs were rather careless about paremeters
that can be set via both an option argument and a positional
argument. This leads to results which can violate the Principal
Of Least Astonishment. These changes refuse to use positional
arguments to override settings that have been made via positional
arguments. The changes are backpatched to all live branches.
The prior coding instructs the user to pick an alternative maintenance
database, but this is overly clever, since it obscures whatever the real
cause of the failure is.

Do not prompt when options were not specified. Assume --no-createdb,
--no-createrole, --no-superuser by default.
Also disable prompting for user name in dropdb, unless --interactive

If unable to connect to "postgres", try "template1". This allows things to
work more smoothly in the case where the postgres database has been
dropped. And just in case that's not good enough, also allow the user to
specify a maintenance database to be used for the initial connection, to
cover the case where neither postgres nor template1 is suitable.

Document thate user/database names are preserved with double-quoting by

most other usage, and it might interfere with a future patch, so I'll
change it all in a separate commit.
Also, replace tabs with spaces for alignment.
In createlang this is a one-line change. In droplang there's a whole
lot of cruft that can be discarded since the extension mechanism now
manages removal of the language's support functions.
Also, add deprecation notices to these two programs' reference pages,
since per discussion we may toss them overboard altogether in a release

linking both executables and shared libraries, and we add on LDFLAGS_EX when

provides a significantly cleaner way of dealing with link-time switches than
the former behavior. Also, make sure that the various platform-specific
%.so: %.o rules incorporate LDFLAGS and LDFLAGS_SL; most of them missed that
before. (I did not add these variables for the platforms that invoke $(LD)
directly, however. It's not clear if we can do that safely, since for the
most part we assume these variables use CC command-line syntax.)

VACUUM FULL INPLACE), along with a boatload of subsidiary code and complexity.
Per discussion, the use case for this method of vacuuming is no longer large
enough to justify maintaining it; not to mention that we don't wish to invest
the work that would be needed to make it play nicely with Hot Standby.
Aside from the code directly related to old-style VACUUM FULL, this commit
removes support for certain WAL record types that could only be generated
within VACUUM FULL, redirect-pointer removal in heap_page_prune, and
nontransactional generation of cache invalidation sinval messages (the last
being the sticking point for Hot Standby).
We still have to retain all code that copes with finding HEAP_MOVED_OFF and
HEAP_MOVED_IN flag bits on existing tuples. This can't be removed as long
as we want to support in-place update from pre-9.0 databases.
If expand_dbname is non-zero and dbname contains an = sign, it is taken as
a conninfo string in exactly the same way as if it had been passed to
PQconnectdb. This is equivalent to the way PQsetdbLogin() works, allowing
PQconnectdbParams() to be a complete alternative.
Also improve the way the new function is called from psql and replace a
previously missed call to PQsetdbLogin() in psql. Additionally use
PQconnectdbParams() for pg_dump and friends, and the bin/scripts
command line utilities such as vacuumdb, createdb, etc.
Finally, update the documentation for the new parameter, as well as the
nuances of precedence in cases where key words are repeated or duplicated
in the conninfo string.
VACUUM FULL was renamed to VACUUM FULL INPLACE. Also added a new
option -i, --inplace for vacuumdb to perform FULL INPLACE vacuuming.
Since the new VACUUM FULL uses CLUSTER infrastructure, we cannot
use it for system tables. VACUUM FULL for system tables always
fall back into VACUUM FULL INPLACE silently.

Procedural languages now have an additional entry point, namely a function

psql's \d commands and other uses of printQuery(). Previously we would pass
these strings through gettext() and then send them to the server as literals
in the SQL query. But the code was not set up to handle doubling of quotes in
the strings, causing failure if a translation attempted to use the wrong kind
of quote marks, as indeed is now the case for (at least) the French
translation of \dFp. Another hazard was that gettext() would translate to
whatever encoding was implied by the client's LC_CTYPE setting, which might be
different from the client_encoding setting, which would probably cause the
server to reject the query as mis-encoded. The new arrangement is to send the
untranslated ASCII strings to the server, and do the translations inside
printQuery() after the query results come back. Per report from Guillaume

renumbering of encoding IDs done between 8.2 and 8.3 turns out to break 8.2
initdb and psql if they are run with an 8.3beta1 libpq.so. For the moment
we can rearrange the order of enum pg_enc to keep the same number for
everything except PG_JOHAB, which isn't a problem since there are no direct
references to it in the 8.2 programs anyway. (This does force initdb
unfortunately.)
Going forward, we want to fix things so that encoding IDs can be changed
without an ABI break, and this commit includes the changes needed to allow
libpq's encoding IDs to be treated as fully independent of the backend's.
The main issue is that libpq clients should not include pg_wchar.h or
otherwise assume they know the specific values of libpq's encoding IDs,
since they might encounter version skew between pg_wchar.h and the libpq.so
they are using. To fix, have libpq officially export functions needed for
encoding name<=>ID conversion and validity checking; it was doing this
anyway unofficially.
It's still the case that we can't renumber backend encoding IDs until the
next bump in libpq's major version number, since doing so will break the
8.2-era client programs. However the code is now prepared to avoid this
type of problem in future.
Note that initdb is no longer a libpq client: we just pull in the two
source files we need directly. The patch also fixes a few places that
were being sloppy about checking for an unrecognized encoding name.

unlike template0 and template1 does not have any special status in
terms of backend functionality. However, all external utilities such
as createuser and createdb now connect to "postgres" instead of
template1, and the documentation is changed to encourage people to use
"postgres" instead of template1 as a play area. This should fix some
longstanding gotchas involving unexpected propagation of database
objects by createdb (when you used template1 without understanding
the implications), as well as ameliorating the problem that CREATE

RedHat 6.2 + perl 5.5.3
* Uses ExtUtils::Embed to find what options are necessary to link with

* createlang is also updated, it can create untrusted perl using 'plperlu'
* Example script (assuming you have Mail::Sendmail installed):
