dots. I previously worked around this in initdb, mapping the known
problematic locale names to aliases that work, but Hiroshi Inoue pointed
out that that's not enough because even if you use one of the aliases, like
"Chinese_HKG", setlocale(LC_CTYPE, NULL) returns back the long form, ie.
"Chinese_Hong Kong S.A.R.". When we try to restore an old locale value by
passing that value back to setlocale(), it fails. Note that you are affected
by this bug also if you use one of those short-form names manually, so just
reverting the hack in initdb won't fix it.
To work around that, move the locale name mapping from initdb to a wrapper
around setlocale(), so that the mapping is invoked on every setlocale() call.
Also, add a few checks for failed setlocale() calls in the backend. These
calls shouldn't fail, and if they do there isn't much we can do about it,
but at least you'll get a warning.
Backpatch to 9.1, where the initdb hack was introduced. The Windows bug
affects older versions too if you set locale manually to one of the aliases,
but given the lack of complaints from the field, I'm hesitent to backpatch.
On closer inspection, whining in restore_toc_entries_parallel is really
much too late for any user-facing error case. The right place to do it
is at the start of RestoreArchive(), before we've done anything interesting
(suh as trying to DROP all the targets ...)
Back-patch to 8.4, where parallel restore was introduced.
If we are unable to do a parallel restore because the input file is stdin
or is otherwise unseekable, we should complain and fail immediately, not
after having done some of the restore. Complaining once per thread isn't
so cool either, and the messages should be worded to make it clear this is
an unsupported case not some weird race-condition bug. Per complaint from
Lonni Friedman.
Back-patch to 8.4, where parallel restore was introduced.
These changes allow backtick command evaluation and psql variable
interpolation to happen on substrings of a single meta-command argument.
Formerly, no such evaluations happened at all if the backtick or colon
wasn't the first character of the argument, and we considered an argument
completed as soon as we'd processed one backtick, variable reference, or
quoted substring. A string like 'FOO'BAR was thus taken as two arguments
not one, not exactly what one would expect. In the new coding, an argument
is considered terminated only by unquoted whitespace or backslash.
Also, clean up a bunch of omissions, infelicities and outright errors in
the psql documentation of variables and metacommand argument syntax.
Per previous experimentation, backtracking slows down lexing performance
significantly (by about a third). It's usually pretty easy to avoid, just
need to have rules that accept an incomplete construct and do whatever the
lexer would have done otherwise.
The backtracking was introduced by the patch that added quoted variable
substitution. Back-patch to 9.0 where that was added.
Rather than dumping out the raw array as PostgreSQL represents it
internally, we now print it out in a format similar to the one in
which the user input it, which seems a lot more user friendly.

When streaming including WAL, the size estimate will always be incorrect,
since we don't know how much WAL is included. To make sure the output doesn't
look completely unreasonable, this patch increases the total size whenever we
go past the estimate, to make sure we never go above 100%.
Instead of displaying comments on an arbitrary subset of the object
types which support them, make \dd display comments on exactly those
object types which don't have their own backlash commands. We now
regard the display of comments as properly the job of the relevant
backslash command (though many of them do so only in verbose mode)
rather than something that \dd should be responsible for. However,
a handful of object types have no backlash command, so make \dd
give information about those.

The relevant backslash commands already exist, so we're just adding an
additional column. With this commit, all objects that have psql backslash
commands and accept comments should now display those comments at least
in verbose mode.
Josh Kupershmidt, with doc additions by me.
\dc and \dD now accept a "+" option, which will cause the comments to
be displayed. Along the way, correct a few oversights in the previous
commit in this area, 3b17efdfdd846c9bfad1637686e6f18198ea3df5 - namely,
(1) when \dL+ is used, make description still be the last column, for
consistency with what we've done elsewhere; and (2) document the
difference between \dC and \dC+.
Josh Kupershmidt, with a couple of doc changes by me.
The output of \dL (list languages) is fairly narrow, so we just always
display the comment. \dC (list casts) can get fairly wide, so we only
display comments if the new \dC+ option is specified.

pg_backup_db.c contained a mini SQL lexer with which it tried to identify
boundaries between SQL commands, but that code was not designed to cope
with standard_conforming_strings, and would get the wrong answer if a
backslash immediately precedes a closing single quote in such a string,
as per report from Julian Mehnle. The bug only affects direct-to-database
restores from archive files made with standard_conforming_strings = on.
Rather than complicating the code some more to try to fix that, let's just
rip it all out. The only reason it was needed was to cope with COPY data
embedded into ordinary archive entries, which was a layout that was used
only for about the first three weeks of the archive format's existence,
and never in any production release of pg_dump. Instead, just rely on the
archive file layout to tell us whether we're printing COPY data or not.
This bug represents a data corruption hazard in all releases in which
standard_conforming_strings can be turned on, ie 8.2 and later, so
back-patch to all supported branches.
Also change "switch" to "arg" because "switch" is a bit of a sloppy
term. So the environment variable is called
PSQL_EDITOR_LINENUMBER_ARG. Set "+" as hardcoded default value on
Unix (since "vi" is the hardcoded default editor), so many users won't
have to configure this at all. Move the documentation around a bit to
centralize the editor configuration under environment variables,
rather than repeating bits of it under every backslash command that
invokes an editor.
This requires a new shared catalog, pg_shseclabel.
Along the way, fix the security_label regression tests so that they
don't monkey with the labels of any pre-existing objects. This is
unlikely to matter in practice, since only the label for the "dummy"
provider was being manipulated. But this way still seems cleaner.
KaiGai Kohei, with fairly extensive hacking by me.
\ir is short for "include relative"; when used from a script, the
supplied pathname will be interpreted relative to the input file,
rather than to the current working directory.
Gurjeet Singh, reviewed by Josh Kupershmidt, with substantial further
cleanup by me.
Most queries end with a backslash, but not a newline, so try to
standardize on that, for the convenience of people using psql -E to
extract queries.

handleCopyIn incremented pset.lineno for each line of COPY data read from
a file. This is correct when reading from the current script file (i.e.,
we are doing COPY FROM STDIN followed by in-line data), but it's wrong if
the data is coming from some other file. Per bug #6083 from Steve Haslam.
Back-patch to all supported versions.
Certain subdirectories do not get built if corresponding options are not
selected at configure time. However, "make distprep" should visit such
directories anyway, so that constructing derived files to be included in
the tarball happens without requiring all configure options to be given
in the tarball build script. Likewise, it's better if cleanup actions
unconditionally visit all directories (for example, this ensures proper
cleanup if someone has done a manual make in such a subdirectory).
To handle this, set up a convention that subdirectories that are
conditionally included in SUBDIRS should be added to ALWAYS_SUBDIRS
instead when they are excluded.
Back-patch to 9.1, so that plpython's spiexceptions.h will get provided
in 9.1 tarballs. There don't appear to be any instances where distprep
actions got missed in previous releases, and anyway this fix requires
gmake 3.80 so we don't want to apply it before 9.1.
DEF_PGPORT already comes in from pg_config.h, so we don't need to pass
it in again with a -D option. Apparently a leftover from the shell
script conversion.
The --flag argument can be used to tell xgettext the arguments of
which functions should be flagged with c-format in the PO files,
instead of guessing based on the presence of format specifiers, which
fails if no format specifiers are present but the translation
accidentally introduces one.
Appropriate flag settings have been added for each message catalog.
based on a patch by Christoph Berg for bug #6066
It currently doesn't make a difference, but it's inconsistent with
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.
For some reason, when we (I) added table lock acquisition to pg_dump,
we didn't think about making it happen as soon as possible after the
start of the transaction. What with subsequent additions, there was
actually quite a lot going on before we got around to that; which sort
of defeats the purpose. Rearrange the order of calls in dumpSchema()
to close the risk window as much as we easily can. Back-patch to all
supported branches.
The short-form -z switch didn't work, for lack of telling getopt_long
about it; and even if specified long-form, it failed to do anything,
because the various tests elsewhere in the file would take
Z_DEFAULT_COMPRESSION (which is -1) as meaning "don't compress".
Per bug #6060 from Shigehiro Honda, though I editorialized on his patch
a bit.
