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.
\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.

"Unusable" collations are those not matching the current database's
encoding. The former behavior inconsistently showed such collations
some of the time, depending on the details of the pattern argument.
Add a new libpq connection option client_encoding (which includes the
existing PGCLIENTENCODING environment variable), which besides an
encoding name accepts a special value "auto" that tries to determine
the encoding from the locale in the client's environment, using the
mechanisms that have been in use in initdb.
psql sets this new connection option to "auto" when running from a
terminal and not overridden by setting PGCLIENTENCODING.

There is still one significant loose end, namely how to make it play nice
with pg_upgrade, so I am not yet committing the changes that would make
all the contrib modules depend on this feature.

Foreign tables are a core component of SQL/MED. This commit does
not provide a working SQL/MED infrastructure, because foreign tables
cannot yet be queried. Support for foreign table scans will need to
be added in a future patch. However, this patch creates the necessary
system catalog structure, syntax support, and support for ancillary
operations such as COMMENT and SECURITY LABEL.

\dn without "S" now hides all pg_XXX schemas as well as information_schema.
Thus, in a bare database you'll only see "public". ("public" is considered
a user schema, not a system schema, mainly because it's droppable.)
Per discussion back in late September.
and the editor's cursor will be initially placed on that line. In \e the
lines are counted with respect to the query buffer, while in \ef they are
counted with line 1 = first line of function body. These choices are useful
for positioning the cursor on the line of a previously-reported error.
To avoid assumptions about what switch the user's editor takes for this
purpose, invent a new psql variable EDITOR_LINENUMBER_SWITCH with (at
present) no default value.
One incompatibility from previous behavior is that "\e 1234" will now
take "1234" as a line number not a file name. There are at least two
ways to select a numerically-named file if you really want to.

The endterm attribute is mainly useful when the toolchain does not support
automatic link target text generation for a particular situation. In the
past, this was required by the man page tools for all reference page links,
but that is no longer the case, and it now actually gets in the way of
proper automatic link text generation. The only remaining use cases are
currently xrefs to refsects.
in the formerly-always-blank columns just to left and right of the data.
Different marking is used for a line break caused by a newline in the data
than for a straight wraparound. A newline break is signaled by a "+" in the
right margin column in ASCII mode, or a carriage return arrow in UNICODE mode.
Wraparound is signaled by a dot in the right margin as well as the following
left margin in ASCII mode, or an ellipsis symbol in the same places in UNICODE
mode. "\pset linestyle old-ascii" is added to make the previous behavior
available if anyone really wants it.
In passing, this commit also cleans up a few regression test files that
had unintended spacing differences from the current actual output.

ASCII-art style of table output to be upgraded to use Unicode box drawing

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

the privileges that will be applied to subsequently-created objects.
Such adjustments are always per owning role, and can be restricted to objects
created in particular schemas too. A notable benefit is that users can
override the traditional default privilege settings, eg, the PUBLIC EXECUTE
privilege traditionally granted by default for functions.

cstring from the output of \df. Now that the default behavior is to
exclude all system functions, the de-cluttering rationale for this behavior
seems pretty weak; and it was always quite confusing/unhelpful if you were
actually looking for I/O functions. (Not to mention if you were looking
for encoding converters or other cases that might take or return cstring.)

This doesn't do any remote or external things yet, but it gives modules
like plproxy and dblink a standardized and future-proof system for

for editing if no function name is specified. This seems a much cleaner way
to offer that functionality than the original patch had. In passing,
de-clutter the error displays that are given for a bogus function-name
argument, and standardize on "$function$" as the default delimiter for the
function body. (The original coding would use the shortest possible
dollar-quote delimiter, which seems to create unnecessarily high risk of
later conflicts with the user-modified function body.)
In support of that, create a backend function pg_get_functiondef().

we might want to re-introduce it as being an alias for -U, but that should
not happen until the switch has actually not been there for a few releases.)

subsequent discussion.
literally, whether quoted or not. Since we allow $ as a character within
identifiers, this behavior is useful, whereas the previous behavior of
treating it as the regexp ending anchor was nearly useless given that the
pattern is automatically anchored anyway. This affects the arguments of
psql's \d commands as well as pg_dump's -n and -t switches. Per discussion.
Standard English uses "may", "can", and "might" in different ways:
may - permission, "You may borrow my rake."
can - ability, "I can lift that log."
might - possibility, "It might rain today."
Unfortunately, in conversational English, their use is often mixed, as
in, "You may use this variable to do X", when in fact, "can" is a better
choice. Similarly, "It may crash" is better stated, "It might crash".

to fix regressions introduced in the recent patch adding additional
\connect options. This is based on work by Volkan YAZICI, although
this version of the patch doesn't bear much resemblance to Volkan's
version.
\connect takes 4 optional arguments: database name, user name, host
name, and port number. If any of those parameters are omitted or
specified as "-", the value of that parameter from the previous
connection is used instead; if there is no previous connection,
the libpq default is used. Note that this behavior makes it
impossible to reuse the libpq defaults without quitting psql and
restarting it; I don't really see the use case for needing to do
that.
(optionally) to a new host and port without exiting psql. This
eliminates, IMHO, a surprise in that you can now connect to PostgreSQL
on a differnt machine from the one where you started your session. This
should help people who use psql as an administrative tool.

psql. i.e. "\pset format troff-ms". The patch also corrects some
problems with the "latex" format, notably defining an extra column in
the output table, and correcting some alignment issues; it also
changes the output to match the border setting as documented in the
manual page and as shown with the "aligned" format.
The troff-ms output is mostly identical to the latex output allowing
for the differences between the two typesetters.
The output should be saved in a file and piped as follows:
cat file | tbl | troff -T ps -ms > file.ps
or
tbl file | troff -T ps -ms > file.ps
Because it contains tabs, you'll need to redirect psql output or use
"script", rather than pasting from a terminal window, due to the tabs
which can be replaced with spaces.
