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
when numericlocale was on.
Backpatch to 8.1 where numericlocale option was added.
This fixes bug #5355 reported by Andy Lester.
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
characters if desired. By default, psql will use the Unicode characters
whenever client_encoding is UTF8.
The patch forces linestyle=ascii in pg_regress usage, ensuring we don't
break the regression tests in Unicode locales.

Provides for better code readability, but mainly this is infrastructure changes
to allow further changes such as arbitrary footers on printed tables. Also,
the translation status of each element in the table is more easily customized.

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
Lelarge and subsequent discussion.
queries via a cursor, fetching a limited number of rows at a time and
therefore not risking exhausting memory. A disadvantage of the scheme
is that 'aligned' output mode will align each group of rows independently
leading to odd-looking output, but all the other output formats work
reasonably well. Chris Mair, with some additional hacking by moi.
mode to only affect the presentation of normal query results, not the
output of psql slash commands. Documentation updated. I also made
some unrelated minor psql cleanup. Per suggestion from Stuart Cooper.
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.

The output now validates as HTML 4.01 Strict, XHTML 1.0 strict,
and XHTML 1.1 (assuming you wrap it in a valid html/body document).
It also wraps the output of PGRES_COMMAND_OK if the HTML tag is on,
for full compliance: this is why html_escaped_print has to be
externalized.

command "\pset pager always" to turn it on. Anything else does the
normal toggle between "on" and "off"

Commented out way old printing functions in libpq
Fixed a typo in alter table / alter column
rate
it's better than what used to be there.
* Does proper SQL "host variable" substitution as pointed out by Andreas
Zeugwetter (thanks): select * from :foo; Also some changes in how ':'
and ';' are treated (escape with \ to send to backend). This does
_not_
affect the '::' cast operator, but perhaps others that contain : or ;
(but there are none right now).
* To show description with a <something> listing, append '?' to command
name, e.g., \df?. This seemed to be the convenient and logical
solution.
Or append a '+' to see more useless information, e.g., \df+.
* Fixed fflush()'ing bug pointed out by Jan during the regression test
discussion.
* Added LastOid variable. This ought to take care of TODO item "Add a
function to return the last inserted oid, for use in psql scripts"
(under CLIENTS)
E.g.,
insert into foo values(...);
insert into bar values(..., :LastOid);
\echo $LastOid
* \d command shows constraints, rules, and triggers defined on the table
(in addition to indices)
* Various fixes, optimizations, corrections
* Documentation update as well
Note: This now requires snprintf(), which, if necessary, is taken from
src/backend/port. This is certainly a little weird, but it should
suffice
until a source tree cleanup is done.
Enjoy.

* Add use of 'const' for varibles in source tree
(which is misspelled, btw.)
I went through the front-end libpq code and did so. This affects in
particular the various accessor functions (such as PQdb() and
PQgetvalue()) as well as, by necessity, the internal helpers they use.
I have been really thorough in that regard, perhaps some people will find
it annoying that things like
char * foo = PQgetvalue(res, 0, 0)
will generate a warning. On the other hand it _should_ generate one. This
is no real compatibility break, although a few clients will have to be
fixed to suppress warnings. (Which again would be in the spirit of the
above TODO.)
In addition I replaced some int's by size_t's and removed some warnings
(and generated some new ones -- grmpf!). Also I rewrote PQoidStatus (so it
actually honors the const!) and supplied a new function PQoidValue that
returns a proper Oid type. This is only front-end stuff, none of the
communicaton stuff was touched.
The psql patch also adds some new consts to honor the new libpq situation,
as well as fixes a fatal condition that resulted when using the -V
(--version) option and there is no database listening.
So, to summarize, the psql you should definitely put in (with or without
the libpq). If you think I went too far with the const-mania in libpq, let
me know and I'll make adjustments. If you approve it, I will also update
the docs.
