pointer type when it is not necessary to do so.
For future reference, casting NULL to a pointer type is only necessary
when (a) invoking a function AND either (b) the function has no prototype
OR (c) the function is a varargs function.

Gerhard Hintermayer, revised and documented by Tom Lane.
This patch also fixes a 'must fix' bug: libpgtcl's LISTEN/NOTIFY
support was broken by the recent changes to the PGnotify structure.
Guess that change wasn't quite so safe as we thought.

PostgreSQL to support unicode-conversion, but retains binary
compatibility among Tcl versions.
However, it neither checks at compile time not at runtime, if support
for unicode-conversion does really exist and it doesn't prevent the
user from changing the client encoding after initialization. I think
there should be warnings about this somewhere in the documentation.

are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.

Made pg_lo_read and pg_lo_write binary data safe when libpgtcl
is compiled against Tcl version 8.0 or higher.

* It works under both Tcl 7.6 and Tcl 8.0 now. (The code claims to
work under Tcl 7.5 as well, but I have no way to test that ---
if anyone still cares, please check it with 7.5.)
* pg_listen suppresses extra LISTEN commands and correctly sends an
UNLISTEN when the last listen request for a relation is cancelled.
(Note this means it will not work with pre-6.4 backends, but that
was true already because it depends on the current libpq, which
only speaks protocol 2.0.)
* Added -error option to pg_result so that there's some way to find
out what you did wrong ;-)
* Miscellaneous cleanups of code comments and overenthusiastic #includes.
BTW, I bumped the package version number from 1.2 to 1.3. Is this
premature? Does someone run around and do that routinely before
each pgsql release?
regards, tom lane

pg_notifies statement is eliminated, and callbacks defined by
pg_listen are instead invoked automatically from the Tcl idle loop
whenever a NOTIFY message is received.
I have done only cursory testing, so there may be problems still
lurking (particularly on non-Unix machines?). But it seems to
work.
Patch is against today's cvs sources. Note that this will not work
with the 6.3.2 release since it depends on the new libpq.
The diffs are a bit large so I've gzipped them. A patch to update
libpgtcl.sgml is included too.

It is my hope that the following "patches" to libpgtcl get included
in the next release.
See the update to the README file to get a full description of the changes.
This version of libpgtcl is completely interpreter-safe, implements the
database connection handle as a channel (no events yet, but will make it
a lot easier to do fileevents on it in the future), and supports the SQL
"copy table to stdout" and "copy table from stdin" commands, with the
I/O being from and to the connection handle. The connection and result
handles are formatted in a way to make access to the tables more efficient.

indenting. Also static variable indenting.

these routines try to use the old pointer casting stuff to get
the connection id, second the notification hash table should
be part of the cliendData. Otherwise, one interpreter might
eat up the notifies for another one.
Please apply the patch below to the current 6.0 tree.

Adds:
-lAttributes
Returns another format of the results attribute list. Per
attribute a sublist of {{attname} atttype attlen} is
returned and an empty string if no attributes where
received.
-numAttrs
Returns the number of attributes in the result.

function so I am going to assume that it is such a good idea that no
one sees any point in discussing it. :-) I have made two changes -
I have merged this into pgtclCmds.c and I have taken out any code for
updating tuples after the loop body runs. See comments for discussion
of this.
I have also fixed up the error checking stuff so that break, continue
and syntax errors have the expected result.
