Attached ia a patch to enable window size detection code of psql for Solaris
platform.
TIOCGWINSZ is defined as follows:
Linux asm/ioctls.h
FreeBSD sys/ttycom.h. This file is included by sys/ioctl.h.
Solaris sys/termios.h
This patch tells print.c to know TIOCGWINSZ on Solaris platform. Same code is
founded in src/bin/psal/common.c.

The fti.pl supplied with the fulltextindex module generate ALL possible
substrings of two characters or greater, and is case-sensitive.
This patch makes it work correctly. It generates only the suffixes of each
word, plus lowercases them - as specified by the README file.
This brings it into line with the fti.c function, makes it case-insensitive
properly, removes the problem with duplicate rows being returned from an fti
search and greatly reduces the size of the generated index table.
It was written by my co-worker, Brett Toolin.

Further thought shows that has_distinct_on_clause() needs to take much
more care with resjunk tlist entries than it was doing. The original
coding ignored resjunk entries entirely, but a resjunk entry that is

ON was used. It's important for ruleutils.c to get this right, else we
may dump views using DISTINCT ON incorrectly.

Change SQL commands embedded in the initdb script from the style
echo "command" | postgres
to the style
postgres <<EOF
command
EOF
This makes the script more legible (IMHO anyway) by reducing the need
to escape quotes, and allows us to execute successive SQL commands in
a single standalone-backend run, rather than needing to start a new
standalone backend for each command. With all the CREATE VIEWs that
are getting done now, this makes for a rather substantial reduction
in the runtime of initdb. (Some of us do initdb often enough to care
how long it runs ;-).)

This patch merges the identical methods from the JDBC1 and JDBC2

their superclass (org.postgresql.Connection).
It also changes the close() methods of Connection and PG_Stream, so that
PG_Stream no longer is responsible for sending the termination packet 'X'
to the backend. I figured that protocol-level stuff like that belonged in
Connection more than in PG_Stream.

Arrange to recycle old XLOG log segment files as new segment files,
rather than deleting them only to have to create more. Steady state
is 2*CHECKPOINT_SEGMENTS + WAL_FILES + 1 segment files, which will
simply be renamed rather than constantly deleted and recreated.
To make this safe, added current XLOG file/offset number to page
header of XLOG pages, so that an un-overwritten page from an old
incarnation of a logfile can be reliably told from a valid page.
This change means that if you try to restart postmaster in a CVS-tip
database after installing the change, you'll get a complaint about
bad XLOG page magic number. If you don't want to initdb, run
contrib/pg_resetxlog (and be sure you shut down the old postmaster
cleanly).

Restructure index AM interface for index building and index tuple deletion,
per previous discussion on pghackers. Most of the duplicate code in
different AMs' ambuild routines has been moved out to a common routine
in index.c; this means that all index types now do the right things about
inserting recently-dead tuples, etc. (I also removed support for EXTEND
INDEX in the ambuild routines, since that's about to go away anyway, and
it cluttered the code a lot.) The retail indextuple deletion routines have
been replaced by a "bulk delete" routine in which the indexscan is inside
the access method. I haven't pushed this change as far as it should go yet,
but it should allow considerable simplification of the internal bookkeeping
for deletions. Also, add flag columns to pg_am to eliminate various
hardcoded tests on AM OIDs, and remove unused pg_am columns.
Fix rtree and gist index types to not attempt to store NULLs; before this,

TODO item:
* Make n of CHAR(n)/VARCHAR(n) the number of letters, not bytes
The attached patch fixes problems with the JDBC driver handling long
null terminated strings. The FE/BE protocol sends in some cases null
terminated strings to the client. The docs for the FE/BE protocol state
that there is no limit on the size of a null terminated string sent to
the client and a client should be coded using an expanding buffer to
deal with large strings. The old code did not do this and gave an error
if a null terminated string was greater than either 4 or 8K. It appears
that with the advent of TOAST very long SQL statements are becoming more
common, and apparently some error messages from the backend include the
SQL statement thus easily exceeding the 8K limit in the old code.
In fixing I also cleaned up some calls in the JDBC fastpath code that
were not doing character set conversion under multibyte, and removed
some methods that were no longer needed. I also removed a potential
threading problem with a shared variable that was being used in
Connection.java.
Thanks to Steve Wampler for discovering the problem and sending the
initial diffs that were the basis of this patch.
