BREAKAGE.
Remove double-quoting of index/table names in reindexdb. BACKWARD
COMPABILITY BREAKAGE.
Document thate user/database names are preserved with double-quoting by
command-line tools like vacuumdb.

We were doing some amazingly complicated things in order to avoid running
the very expensive identify_system_timezone() procedure during GUC
initialization. But there is an obvious fix for that, which is to do it
once during initdb and have initdb install the system-specific default into
postgresql.conf, as it already does for most other GUC variables that need
system-environment-dependent defaults. This means that the timezone (and
log_timezone) settings no longer have any magic behavior in the server.
Per discussion.

When building a GiST index that doesn't fit in cache, buffers are attached
to some internal nodes in the index. This speeds up the build by avoiding
random I/O that would otherwise be needed to traverse all the way down the
tree to the find right leaf page for tuple.

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.

As in the backend, the implementation actually accepts any non-ASCII
character, but we only document that you can use letters.

Along the way, rename "Options" to "FDW Options" in various places for
consistency and clarity.

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+.

Almost all other pages have one; this one must have been forgotten.

There is what may actually be a mistake in our markup. The problem is
in a situation like
<para>
<command>FOO</command> is ...
there is strictly speaking a line break before "FOO". In the HTML
output, this does not appear to be a problem, but in the man page
output, this shows up, so you get double blank lines at odd places.
So far, we have attempted to work around this with an XSL hack, but
that causes other problems, such as creating run-ins in places like
<acronym>SQL</acronym> <command>COPY</command>
So fix the problem properly by removing the extra whitespace. I only
fixed the problems that affect the man page output, not all the
places.

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.

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.

\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.

This means that they can initially be added to a large existing table
without checking its initial contents, but new tuples must comply to
them; a separate pass invoked by ALTER TABLE / VALIDATE can verify
existing data and ensure it complies with the constraint, at which point
it is marked validated and becomes a normal part of the table ecosystem.
An non-validated CHECK constraint is ignored in the planner for
constraint_exclusion purposes; when validated, cached plans are
recomputed so that partitioning starts working right away.
This patch also enables domains to have unvalidated CHECK constraints
attached to them as well by way of ALTER DOMAIN / ADD CONSTRAINT / NOT
VALID, which can later be validated with ALTER DOMAIN / VALIDATE
CONSTRAINT.
Thanks to Thom Brown, Dean Rasheed and Jaime Casanova for the various
reviews, and Robert Hass for documentation wording improvement
suggestions.

We had previously (af26857a2775e7ceb0916155e931008c2116632f)
established the U.S. spellings as standard.

Per Josh Kupershmidt and Tom Lane.
|
|
The initial commit of the ALTER TABLE ADD FOREIGN KEY NOT VALID feature
failed to support labeling such constraints as deferrable. The best fix
for this seems to be to fold NOT VALID into ConstraintAttributeSpec.
That's a bit more general than the documented syntax, but it allows
better-targeted syntax error messages.
In addition, do some mostly-but-not-entirely-cosmetic code review for
the whole NOT VALID patch.
|
|
This has always been true, it was just never documented.
|
|
Per a gripe from Tom Lane.
|
|
The previous wording wasn't explicit enough, which could misled readers
into thinking that the locks acquired are more restricted in nature than
they really are. The resulting optimism can be damaging to morale when
confronted with reality, as has been observed in the field.

Since start/stop/restart/reload/status is a kind of standard command
set, it seems odd to insert the special-purpose "promote" in between
the closely related "restart" and "reload". So put it after "status"
in code and documentation.
Put the documentation of the -U option in some sensible place.
Rewrite the synopsis sentence in help and documentation to make it
less of a growing mouthful.

For the --help output and reference pages of pg_dump, pg_dumpall,
pg_restore, put the options in some consistent, mostly alphabetical,
and consistent order, rather than newest option last or something like
that.

Other similar options also use the plural form.

This commit fixes psql, pg_dump, and the information schema to be
consistent with the backend changes which I made as part of commit
be90032e0d1cf473bdd99aee94218218f59f29f1, and also includes a
related documentation tweak.
