If set, the pager will not be used unless this many lines are to be
displayed, even if that is more than the screen depth. Default is zero,
meaning it's disabled.
There is probably more work to be done in giving the user control over
when the pager is used, particularly when wide output forces use of the
pager regardless of how many lines there are, but this is a start.
This error counted the first line of a cell as "extra". The effect was
to cause far too frequent invocation of the pager. In most cases this
can be worked around (for example, by using the "less" pager with the -F
flag), so don't backpatch.
With the unicode linestyle, this adds support to control if the
column, header, or border style should be single or double line
unicode characters. The default remains 'single'.
In passing, clean up the border documentation and address some
minor formatting/spelling issues.
Pavel Stehule, with some additional changes by me.
In psql, expanded mode was not being displayed correctly when using
the normal ascii or unicode linestyles and border set to '3'. Now,
per the documentation, border '3' is really only sensible for HTML
and LaTeX formats, however, that's no excuse for ascii/unicode to
break in that case, and provisions had been made for psql to cleanly
handle this case (and it did, in non-expanded mode).
This was broken when ascii/unicode was initially added a good five
years ago because print_aligned_vertical_line wasn't passed in the
border setting being used by print_aligned_vertical but instead was
given the whole printTableContent. There really isn't a good reason
for vertical_line to have the entire printTableContent structure, so
just pass in the printTextFormat and border setting (similar to how
this is handled in horizontal_line).
Pointed out by Pavel Stehule, fix by me.
Back-patch to all currently-supported versions.

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.

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.
When there are zero result rows, in expanded mode, "(No rows)" is
printed. So far, there was no way to turn this off. Now, when
tuples-only mode is turned on, nothing is printed in this case.
Remove extra line at bottom of table for new 'latex' mode border=3.
Also update 'latex'-longtable 'tableattr' docs to say
'whitespace-separated' instead of 'space'.
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.)
Due to an apparent thinko, when printing a table in expanded mode
(\x), space would be allocated for 1 slot plus 1 byte per line,
instead of 1 slot per line plus 1 slot for the NULL terminator. When
the line count is small, reading or writing the terminator would
therefore access memory beyond what was allocated.
Add new psql settings and command-line options to support setting the
field and record separators for unaligned output to a zero byte, for
easier interfacing with other shell tools.

This adds the "auto" option to the \x command, which switches to the
expanded mode when the normal output would be wider than the screen.

This addresses only those cases that are easy to fix by adding or
moving a const qualifier or removing an unnecessary cast. There are
many more complicated cases remaining.
My initial impression that glibc was measuring the precision in characters
(which is what the Linux man page says it does) was incorrect. It does take
the precision to be in bytes, but it also tries to truncate the string at a
character boundary. The bottom line remains the same: it will mess up
if the string is not in the encoding it expects, so we need to avoid %.*s
anytime there's a significant risk of that. Previous code changes are still
good, but adjust the comments to reflect this knowledge. Per research by
Hernan Gonzalez.
Depending on which spec you read, field widths and precisions in %s may be
counted either in bytes or characters. Our code was assuming bytes, which
is wrong at least for glibc's implementation, and in any case libc might
have a different idea of the prevailing encoding than we do. Hence, for
portable results we must avoid using anything more complex than just "%s"
unless the string to be printed is known to be all-ASCII.
This patch fixes the cases I could find, including the psql formatting
failure reported by Hernan Gonzalez. In HEAD only, I also added comments
to some places where it appears safe to continue using "%.*s".
formats; a null string must not be formatted as a numeric. The more exotic
formats latex and troff also incorrectly formatted all strings as numerics

Backpatch to 8.1 where numericlocale option was added.
This fixes bug #5355 reported by Andy Lester.
(failure to free col_lineptrs[] array elements) and exacerbated in the
current devel cycle (failure to free "wrap"). This resulted in moderate
bloat of psql over long script runs. Noted while testing bug #5302,

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.
