function's comment if the operator has no comment of its own, to preserve
the useful functionality of the original behavior. Also, implement
COMMENT ON SCHEMA. Patch from Rod Taylor.
Apparently, you need to make two calls to appendPQExpBuffer() to
use fmtId() twice, because it uses a static buffer (thanks for
spotting this Tom).
Another revision of the patch is attached.

DROP RULE and COMMENT ON RULE syntax adds an 'ON tablename' clause,
similar to TRIGGER syntaxes. To allow loading of existing pg_dump
files containing COMMENT ON RULE, the COMMENT code will still accept
the old syntax --- but only if the target rulename is unique across
the whole database.
some old code to add PK constraints to CREATE TABLE. That stuff
had been removed as part of my original patch for pg_dump a
little while ago.
The attached patch fixes this by removing (again :-) ) the
code in dumpTables() to perform PK creation during CREATE
TABLE. I briefly tested it locally and it fixes both of
Tom's test cases.
Please apply.
Cheers,

namespaces, and also simplifies/speeds up lookup in parse_func.c.
Also, add a 'proimplicit' flag to pg_proc that controls whether a type
coercion function may be invoked implicitly, or only explicitly. The
current settings of these flags are more permissive than I would like,
but we will need to debate and refine the behavior; for now, I avoided
breaking regression tests as much as I could.

Also, add a pronamespace column to pg_proc (it doesn't do anything yet,
however).

Also improve a couple of error messages about inconsistencies.

- Fix handling of {data/schema}-only restores when using a full
backup file; prior version was restoring schema in data-only
restores. Added enum to make code easier to understand.
(why bother dropping individual objects in a just-created database?)
as well as dangerous (as the code stands, the drops will be issued in
the wrong database, namely the one you were originally connected to).
the entered password would get echoed on some platforms, eg HPUX.
We have enough copies of this code that I'm thinking it ought to be
moved into libpq, but that's a task for another day.
'aggname (aggtype)'. The old syntax 'aggname aggtype' is still accepted
for backwards compatibility. Fix pg_dump, which was actually broken for
most cases of user-defined aggregates. Clean up error messages associated
with these commands.
pg_get_indexdef() function, rather than reaching into the system catalogs
for itself. This eliminates a fair amount of redundant code. Also,
since I just changed pg_get_indexdef() to suppress display of default
index opclasses, this will mean that 7.2 and later dumps will not mention
opclasses unless they are non-default opclasses. Should make life easier
for future index opclass reorganizations.
If there's anyone out there who's actually using datatype-defined
default values, this will be an incompatible change in behavior ...
but the old behavior was so broken that I doubt anyone was using it.
for some reason displays a zero oid differently. Possibly we should
revert that schema change, but it's easy to make pg_dump accept both
spellings so I'll do that for now.
buffer manager with 'pg_clog', a specialized access method modeled
on pg_xlog. This simplifies startup (don't need to play games to
open pg_log; among other things, OverrideTransactionSystem goes away),
should improve performance a little, and opens the door to recycling
commit log space by removing no-longer-needed segments of the commit
log. Actual recycling is not there yet, but I felt I should commit
this part separately since it'd still be useful if we chose not to
do transaction ID wraparound.

initdb forced. Note this also breaks any chance of pg_upgrade from 7.1,
unless we hack up pg_upgrade to drop and recreate sequences. (Which is
not out of the question, but I don't wanna do it.)
Don't hardcode the maximum accepted server version, use PG_VERSION instead.
Install a notice processor so notices are handled like error messages.
Word smithing.
default, but OIDS are removed from many system catalogs that don't need them.
Some interesting side effects: TOAST pointers are 20 bytes not 32 now;
pg_description has a three-column key instead of one.
Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey
has some usefulness; pg_dump dumps comments on indexes, rules, and
triggers in a valid order.
initdb forced.
Dump the alignment and storage information for user-defined types (how'd
that manage to slip through the cracks?), and don't dump 'shell' types
that don't have typisdefined set. Fix badly broken logic for dependencies
of type definitions (did not work for more than one user-defined type...).
Avoid memory leakage within pg_dump by being more careful to release
storage used by PQExpBuffer objects.
Note: I didn't force an initdb, figuring that one today was enough.
However, there is a new function in pg_proc.h, and pg_dump won't be
able to dump partial indexes until you add that function.
--verbose messages, which had not been considered so far. Output to the

Clean up some slightly grotty coding in 7.0 pg_class reading, also.
- Fix view dumping SQL for V7.0
- Fix bug when getting view oid with long view names
- Treat SEQUENCE SET TOC entries as data entries rather than schema
entries.
- Make allowance for data entries that did not have a data dumper
routine (eg. SEQUENCE SET)
the UDT/function order problem.
- Rudimentary support for dependencies in archives.
Uses dependencies to modify the OID used in sorting TOC
entries. This will NOT handle multi-level dependencies,
but will manage simple relationships like UDTs & their functions.
- Treat OIDs with more respect (avoid using ints, use macros
for conversion & comparison).
- Avoid forcing table name to lower case in FixupBlobXrefs
- Removed fmtId calls for all ArchiveEntry name fields. This fixes
quoting problems in trigger enable/disable code for mixed case
table names, and avoids commands like 'pg_restore -t '"TblA"'
- Add extra arg to formatStringLiteral to specify how to handle LF & TAB.
I opted for encoding them except in procedure bodies & comments
- Fixed bug in tar file input when restoring blobs
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.
Ok. I have made patches for fixing some of pg_dump problems(see
attached patches). The patches address the problem with user defined
functions, operators and aggregates.
- Fix handling of --tables=* (multiple tables never worked properly, AFAICT)
- strdup() the current user in DB routines
- Check results of IO routines more carefully.
- Check results of PQ routines more carefully.
Have not fixed index output yet.

case it's better than having a dozen different ones in the tree.
cloned, rather than always cloning template1. Modify initdb to generate
two identical databases rather than one, template0 and template1.
Connections to template0 are disallowed, so that it will always remain
in its virgin as-initdb'd state. pg_dumpall now dumps databases with
restore commands that say CREATE DATABASE foo WITH TEMPLATE = template0.
This allows proper behavior when there is user-added data in template1.
initdb forced!
hosting product, on both shared and dedicated machines. We currently
offer Oracle and MySQL, and it would be a nice middle-ground.
However, as shipped, PostgreSQL lacks the following features we need
that MySQL has:
1. The ability to listen only on a particular IP address. Each
hosting customer has their own IP address, on which all of their
servers (http, ftp, real media, etc.) run.
2. The ability to place the Unix-domain socket in a mode 700 directory.
This allows us to automatically create an empty database, with an
empty DBA password, for new or upgrading customers without having
to interactively set a DBA password and communicate it to (or from)
the customer. This in turn cuts down our install and upgrade times.
3. The ability to connect to the Unix-domain socket from within a
change-rooted environment. We run CGI programs chrooted to the
user's home directory, which is another reason why we need to be
able to specify where the Unix-domain socket is, instead of /tmp.
4. The ability to, if run as root, open a pid file in /var/run as
root, and then setuid to the desired user. (mysqld -u can almost
do this; I had to patch it, too).
The patch below fixes problem 1-3. I plan to address #4, also, but
haven't done so yet. These diffs are big enough that they should give
the PG development team something to think about in the meantime :-)
Also, I'm about to leave for 2 weeks' vacation, so I thought I'd get
out what I have, which works (for the problems it tackles), now.
With these changes, we can set up and run PostgreSQL with scripts the
same way we can with apache or proftpd or mysql.
In summary, this patch makes the following enhancements:
1. Adds an environment variable PGUNIXSOCKET, analogous to MYSQL_UNIX_PORT,
and command line options -k --unix-socket to the relevant programs.
2. Adds a -h option to postmaster to set the hostname or IP address to
listen on instead of the default INADDR_ANY.
3. Extends some library interfaces to support the above.
4. Fixes a few memory leaks in PQconnectdb().
The default behavior is unchanged from stock 7.0.2; if you don't use
any of these new features, they don't change the operation.

kibitzing from Tom Lane. Large objects are now all stored in a single
system relation "pg_largeobject" --- no more xinv or xinx files, no more
relkind 'l'. This should offer substantial performance improvement for
large numbers of LOs, since there won't be directory bloat anymore.
It'll also fix problems like running out of locktable space when you
access thousands of LOs in one transaction.
Also clean up cruft in read/write routines. LOs with "holes" in them
(never-written byte ranges) now work just like Unix files with holes do:
a hole reads as zeroes but doesn't occupy storage space.

might have used ".". (Regression tests don't work with this, yet.)
Sort out usage of CPPFLAGS, CFLAGS (and CXXFLAGS). Add "override" keyword

DESTDIR=/else/where' and prepends the value of DESTDIR to the full
installation paths (e.g., /else/where/usr/local/pgsql/bin). This allows
users to install the package into a location different from the one that
was configured and hard-coded into various scripts, e.g., for creating
binary packages.
DESTDIR is in many cases preferrable over `make install
prefix=/else/where' because
a) `prefix' affects the path that is hard-coded into the files, which can
lead to a `make install prefix=xxx' (as done by the regression test
driver) corrupting the files in the source tree with wrong paths.
b) it doesn't work at all if a directory was overridden to not depend on
`prefix', e.g., --sysconfdir=/etc.
(Updating the regression test driver to use DESTDIR is a separate
undertaking.)

Here's the multibyte aware version of my patch to fix the truncation
of the rulename autogenerated during a CREATE VIEW. I've modified all
the places in the backend that want to construct the rulename to use
the MakeRetrieveViewRuleName(), where I put the #ifdef MULTIBYTE, so
that's the only place that knows how to construct a view rulename. Except
pg_dump, where I replicated the code, since it's a standalone binary.
The only effect the enduser will see is that views with names len(name)
> NAMEDATALEN-4 will fail to be created, if the derived rulename clases
with an existing rule: i.e. the user is trying to create two views with
long names whose first difference is past NAMEDATALEN-4 (but before
NAMEDATALEN: that'll error out after the viewname truncation.) In no
case will the user get left with a table without a view rule, as the
current code does.

NULL handling in aggregates is a lot cleaner. Also, use Numeric

1) adds NetBSD shared lib support on both ELF and a.out platforms
2) replaces "-L$(LIBPQDIR) -lpq" with "$(LIBPQ)" defined in
Makefile.global. This makes it much easier to build stuff in
the source tree after you've already installed the libraries.
3) adds TEMPLATEDIR in Makefile.global that indicates where the
database templates are stored. This separates the template files
from real libraries that are installed in $(LIBDIR).
4) changes include order of <readline/readline.h> and <readline.h>.
The latest GNU readline installs its headers under a readline
subdirectory.
In addition to applying the patch below the following files need to be copied:
backend/port/dynloader:
bsd.h -> netbsd.h
bsd.c -> netbsd.c
include/port:

It would be great to see this incorporated into the source tree before
the 7.0 release is cut.

oidvector/int2vector. pg_dump code was assuming that it would see
exactly FUNC_MAX_ARGS integers in the string returned by the backend.
That's no longer true. (Perhaps that change wasn't such a good idea
after all --- will it break any other applications??)
I finally got around to schlepping through pg_dump, to finish what I started
about three months (or more) ago. Attached is a gzipped diff file to apply
in the bin/pg_dump directory. This should remove all string length
dependencies, except one, which I'm working on. It has been through some
rudimentary unit testing, but that's about it, so if any of you would give
it a more strenuous run-through, I'd be grateful for the feedback.
Cheers...

structs from libpq-fe.h, as we previously discussed.
There turned out to be sloppy coding practices in more places than
I had realized :-(, but all in all I think it was a well-worth-while
exercise.
I ended up adding several routines to libpq's API in order to respond
to application requirements that were exposed by this work. I owe the
docs crew updates for libpq.sgml to describe these changes. I'm way too
tired to work on the docs tonight, however.
This is the last major change I intend to submit for 6.4. I do want
to see if I can make libpgtcl work with Tcl 8.0 before we go final,
but hopefully that will be a minor bug fix.
ODBC driver have found a bug in 6.3.2 pg_dump and have made patches.
I confirmed that the same bug still exists in the current source
tree. So I made up patches based on Kataoka's. Here are some
explanations.
o fmtId() returns pointer to a static memory in it. In the meantime
there is a line where is fmtId() called twice without saving the
first value returned by fmtId(). So second call to fmtId() will
break the first one.
o findTableByName() looks up a table by its name. if a table name
contanins upper letters or non ascii chars, fmtId() will returns
a name quoted in double quotes, which will not what findTableByName()
wants. The result is SEG fault. -- Tatsuo Ishii t-ishii@sra.co.jp
if MULTIBYTE is not enabled. So be sure to run initdb.
o these patches are made against the latest source tree (after
Bruce's massive patch, I think) BTW, I noticed that after running
regression, the oid field of pg_type seems disappeared.
regression=> select oid from pg_type; ERROR: attribute
'oid' not found
this happens after the constraints test. This occures with/without
my patches. strange...
o pg_database_mb.h, pg_class_mb.h, pg_attribute_mb.h are no longer
used, and shoud be removed.
o GetDatabaseInfo() in utils/misc/database.c removed (actually in
#ifdef 0). seems nobody uses.

of days --- it was emitting stuff like
REVOKE ALL on 'table' from PUBLIC; GRANT ALL on "table" to
"Public"; neither of which work. While I was at it I
cleaned up a few other things:
* \connect commands are issued only in -z mode. In this way,
reloading a pg_dump script made without -z will generate a simple
database wholly owned by the invoking user, rather than a mishmash
of tables owned by various people but lacking in access rights.
(Analogy: cp versus cp -p.)
* \connect commands are issued just before COPY FROM stdin commands;
without this, reloading a database containing non-world-writable
tables tended to fail because the COPY was not necessarily attempted
as the table owner.
* Redundant \connect commands are suppressed (each one costs a
backend launch, so...).
* Man page updated (-z wasn't ever documented).

owners") but no one had bothered to deal with 'em yet.

I see someone missed an ancient bit of shell-scripting lore:
on some older shells, if your script's argument list is empty,
then "$@" generates an empty-string word rather than no word
at all. You need to write ${1+"$@"} to get the latter behavior.
(Read your shell man page to see exactly how that works,
but it does the Right Thing on every Bourne shell.)
In particular, pg_dumpall fails when invoked without any switches
on HPUX 9.*, because pg_dump gets an empty-string argument that it
thinks is the name of the database to dump. I expect this bug
also affects some other OSes, but couldn't tell you just which ones.
Patch attached.
I have implemented a framework of encoding translation between the
backend and the frontend. Also I have added a new variable setting
command:
SET CLIENT_ENCODING TO 'encoding';
Other features include:
Latin1 support more 8 bit cleaness
See doc/README.mb for more details. Note that the pacthes are
against May 30 snapshot.

syntax that can be read back in with psql. I did this by adding
a
"-c" switch that controls moving the CONTSTRAINT statements inside
the CREATE TABLE statements and adding () around the CHECK arguments.
Here's diffs against the 6.3.2 version of pg_dump.c.

Attached you'll find a (big) patch that fixes make dep and make
depend in all Makefiles where I found it to be appropriate.
It also removes the dependency in Makefile.global for NAMEDATALEN
and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh
a little smarter.
This no longer requires initdb.sh that is turned into initdb with
a sed script when installing Postgres, hence initdb.sh should be
renamed to initdb (after the patch has been applied :-) )
This patch is against the 6.3 sources, as it took a while to
complete.
Please review and apply,
Cheers,

yyerror ones from bison. It also includes a few 'enhancements' to
the C programming style (which are, of course, personal).
The other patch removes the compilation of backend/lib/qsort.c, as
qsort() is a standard function in stdlib.h and can be used any
where else (and it is). It was only used in
backend/optimizer/geqo/geqo_pool.c, backend/optimizer/path/predmig.c,
and backend/storage/page/bufpage.c

There's more to come. Please review these patches. I ran the
regression tests and they only failed where this was expected
(random, geo, etc).

varchar length.
Cleans up code so attlen is always length.
Removed varchar() hack added earlier.
Will fix bug in selecting varchar() fields, and varchar() can be
variable length.
src. It is in the function ParseACL. When I find that I
can not allocate enough memory for the ACL structure I
return an NULL instead of doing an exit_nicely(g_conn);

Clean up formatting of code
Integrate new functions into dumpTable
This is not tested yet...have to recompile server due to patches from
Todd...but this compiles cleanly as it stands now
Subject: [PATCHES] pg_dump memory leak patch
This patch fixes a HUGE memory leak problem in pg_dump.
Pretty much anything that was allocated was never freed and Purify
reported about 40% possible memory leak and 6% actual leak. I added
functions to clear out all the allocated structures. After the patch
Purify returns 0 for number of bytes leaked...
Subject: [PATCHES] Three small patches.
Hi,
Here are 3 small patches to the postgreSQL source sup'd on
the 6th May 1997.
The 1st 2 fix the shell backslash "c" handling used to suppress
the newline on some unix shells. (The \c needs to be inside quote.)
The 3rd may or may not be the correct way to fix the missing
define of INDEX_MAX_KEYS in pg_dump.h
FreeBSD
The Makefile(s) have all been cleaned up such that there is a single
LDFLAGS vs LD_ADD or LDADD or LDFLAGS or LDFLAGS_BE. The Makefile(s)
should be alot more straightforward then they were before...and
consistent
Add a check to configure for strdup
Remove all the '-ltermcap' checks from psql/Makefile
Have {psql,pg_dump}/Makefile modified if strdup doesn't exist on the system
|by neglecting to quote them.
|
|I have made a minor change to pg_dump.c that will fix this.
|
|Dates are dumped and restored OK with pg_dump in V6
|
|We'll still need to fix the dump in both cases if the original dump is from V1.09.

It adds a WITH OIDS option to the copy command, which allows
dumping and loading of oids.
If a copy command tried to load in an oid that is greater than
its current system max oid, the system max oid is incremented. No
checking is done to see if other backends are running and have cached
oids.
pg_dump as its first step when using the -o (oid) option, will
copy in a dummy row to set the system max oid value so as rows are
loaded in, they are certain to be lower than the system oid.
pg_dump now creates indexes at the end to speed loading

pg_dump and load to 2.0. I haven't gotten any feedback on whether
people want it, so I am submitting it for others to decide. I would
recommend an install in 1.02.1.
I had said that the 2.0 pg_dump could dump a 1.02.1 database, but I was
wrong. The copy is actually performed by the backend, and the 2.0
database will not be able to read 1.02.1 databases because of the new
system columns.
This patch does several things. It copies nulls out as \N, so they can
be distinguished from '' strings. It fixes a problem where backslashes
in the input stream were not output as double-backslashes. Without this
patch, backslashes copied out were deleted upon input, or interpreted as
special characters. Third, input is now terminated by backslash-period.
This can not be part of a normal input stream.
I tested this by creating a database with all sorts of nulls, backslash,
and period fields and dumped the database and reloaded into a new
database and compared them.

case where the attribute length is variable (stored as -1). Previously,
you'd get output that looked like:
CREATE TABLE foo (bar varchar(-1));
Monitor and psql don't like this at all :). Here is a fix:
