owned by postgres, doing "pg_ctl start" as root could allow a privilege
escalation attack, as pointed out by iDEFENSE. Of course the postmaster would
fail, but we ought to fail a little sooner to protect sysadmins unfamiliar
with Postgres. The chosen fix is to disable root use of pg_ctl in all cases,
just to be confident there are no other holes.

- refactor a bunch of code to call a separate function print_msg() which
checks whether "silent mode" is enabled before printing an error
message.
- rename "silence_mode" to "silent_mode", which IMHO makes more sense
- make the error messages we emit in "waiting" mode more consistent; I
believe this fixes a recent error message regression
- replace some function signatures of the form "some_type foo()" with
"some_type foo(void)"
- replace a few instances of a literal 0 being used as a NULL pointer;
there are more instances of this in the code, but I just fixed a few
- in src/backend/utils/mb/wstrncmp.c, replace K&R style function
declarations with ANSI style, remove use of 'register' keyword
- remove an "extern" modifier that was applied to a function definition

some possible causes of the stale postmaster.pid problem that some users
have reported.
- The service did not properly report that it accepts
SERVICE_CONTROL_SHUTDOWN events, thus it's possible the SCM simply
killed the postmaster on shutdown.
- 'WaitHints' are now given to the SCM to prevent it timing out if
pg_ctl doesn't respond to a control event quickly enough.
- During shutdown, the service checkpoint counter is incremented every
five seconds for up to a minute to prevent the SCM timing out and
assuming the service is not responding.

multiline command or to rerun the command easily later.
Whereas displaying the failed SQL command is a matter of fixing the
error
messages.
The latter is complicated by failed COPY commands which, with
die-on-errors
off, results in the data being processed as a command, so dumping the
command will dump all of the data.
In the case of long commands, should the whole command be dumped? eg.
(eg.
several pages of function definition).
In the case of the COPY command, I'm not sure what to do. Obviously, it
would be best to avoid sending the data, but the data and command are
combined (from memory). Also, the 'data' may be in the form of INSERT
statements.

to/in the psql-tabcomplete code. This diff includes the still missing
tab-complete support for TABLESPACE I already sent earlier. New in this
version of the patch is a small adaption of the tab-complete code to
support the adjusted SAVEPOINT-Syntax commited by Tom, as well as
completion of the only half working (and I think only by accident)
tabcomplete-suppport for "BEGIN [ TRANSACTION | WORK ]".
below is a complete list of the things I have changed with this patch:
*) add tablespace support for CREATE/DROP/ALTER and \db
*) sync the list of possible commands following ALTER with the docs (by
adding
AGGREGATE,CONVERSATION,DOMAIN,FUNCTION,LANGUAGE,OPERATOR,SEQUENCE,TABLESPACE
and TYPE)
*) provide a list of valid users after "OWNER TO"
*) tab-complete support for ALTER (AGGREGATE|CONVERSION|FUNCTION)
*) basic tab-complete support for ALTER DOMAIN
*) provide a list of suitable indexes following ALTER TABLE <sth>
CLUSTER ON(?)
*) add "CLUSTER ON" and "SET" to the ALTER TABLE <sth> - tab-complete
list(fixes incorrect/wrong tab-complete with ALTER TABLE <sth> SET
+<TAB> too)
*) provide a list of possible indexes following ALTER TABLE <sth> CLUSTER ON
*) provide list of possible commands(WITHOUT CLUSTER,WITHOUT OIDS,
TABLESPACE) following ALTER TABLE <sth> SET
*) sync "COMMENT ON" with docs by adding "CAST","CONVERSION","FUNCTION"
*) add ABSOLUT to the list of possible commands after FETCH
*) "END" was missing from the sql-commands overview (though it had
completion support!) - i know it's depreciated but we have ABORT and
others still in ...
*) fixes small buglet with ALTER (TRIGGER|CLUSTER) ON autocomplete
(CLUSTER ON +<TAB> would produce CLUSTER ON ON - same for TRIGGER ON)
*) adapt to new SAVEPOINT syntax
*) fix incomplete Support for BEGIN [ TRANSACTION | WORK ]

of '.' or '..'. Extend canonicalize_path() to trim off trailing occurrences
of these things, and use it to fix up paths where needed (which I think is
only after places where we trim the last path component, but maybe some
others will turn up). Fixes Josh's complaint that './initdb' does not
work.
CurrentMemoryContext is DLLIMPORT on Win32. Work around that by
creating stubs in the backend for palloc/pstrdup.
Also fix pg_dumpall to do proper quoting on Win32.
o "_" is not escaped, and causes TeX to abort, thinking it's a
subscript outside of maths mode. Most of my table and field names
use underscores, so this is a really nasty one.
o The column count is calculated using the contents of opt_align. But
opt_align has one extra element, and so it's always one too many. I
changed it to count the column headings, like all the other output
formats. There may be a bug in computing opt_align that this patch
does not address, but I'm not yet familiar enough with the psql
source to fix this as well.
o The line drawing rules for each border setting (0-3) and expanded
mode didn't always match the documented behaviour and what other
formats (e.g. aligned) did. I made it as conformant as possible,
and also tidied the alignment of the first line of the footer, which
was incorrectly indented.

Instead of putting all the OWNER TO commands at the end, it dumps then

at the end.

password/group files. Also allow read-only subtransactions of a read-write

This should fix the boundary-case bugs observed by Mark Kirkwood.
initdb forced due to change of XLOG representation.
* Fix help text ordering
* Add back --set-session-authorization to pg_dumpall. Updated the docs
for that. Updated help for that.
* Dump ALTER USER commands for the cluster owner ("pgsql"). These are
dumped AFTER the create user and create database commands in case the
permissions to do these have been revoked.
* Dump ALTER OWNER for public schema (because it's possible to change
it). This was done by adding TOC entries for the public schema, and
filtering them out at archiver time. I also save the owner in the TOC
entry just for the public schema.
* Suppress dumping single quotes around schema_path and DateStyle
options when they are set using ALTER USER or ALTER DATABASE. Added a
comment to the steps in guc.c to remind people to update that list.
* Fix dumping in --clean mode against a pre-7.3 server. It just sets
all drop statements to assume the public schema, allowing it to restore
without error.
* Cleaned up text output. eg. Don't output -- Tablespaces comment if
there are none. Same for groups and users.
* Make the commands to DELETE FROM pg_shadow and DELETE FROM pg_group
only be output when -c mode is enabled. I'm not sure why that hasn't
been done before?!?!
This should be good for application asap, after which I will start on
regression dumping 7.0-7.4 databases.

I kept the same abbreviated letter -D, in hopes of maintaining some
modicum of backwards compatibility (though it's doubtful whether anyone
is really using scripts that invoke createdb -D ...)
There are various things left to do: contrib dbsize and oid2name modules
need work, and so does the documentation. Also someone should think about
COMMENT ON TABLESPACE and maybe RENAME TABLESPACE. Also initlocation is
dead, it just doesn't know it yet.

copied by the script that generates psql's help. (You can get the
spurious CRs if you use a CVS client on Windows that does line end

extensive change then what was suggested. I found the file path.c that
contained a lot of "Unix/Windows" agnostic functions so I added a function
there instead and removed the PATHSEP declaration in exec.c altogether. All
to keep things from scattering all over the code.
I also took the liberty of changing the name of the functions
"first_path_sep" and "last_path_sep". Where I come from (and I'm apparently
not alone given the former macro name PATHSEP), they should be called
"first_dir_sep" and "last_dir_sep". The new function I introduced, that
actually finds path separators, is now the "first_path_sep". The patch
contains changes on all affected places of course.
I also changed the documentation on dynamic_library_path to reflect the
chagnes.

environment variable processing to libpq.
The patch also adds code to our client apps so we set the environment
variable directly based on our binary location, unless it is already
set. This will allow our applications to emit proper locale messages
that are generated in libpq.
It was necessary to touch in grammar and create a new node to make home
to the new syntax. The command is also supported in E
CPG. Doc updates are attached too. Only superusers can change the owner
of the database. New owners don't need any aditional
privileges.

Remove elog() calls from find_my_exec; do fprintf(stderr) instead. We

all the code that looks for other binaries. I move FindExec into
port/exec.c (and renamed it to find_my_binary()). I also added
find_other_binary that looks for another binary in the same directory as
the calling program, and checks the version string.
The only behavior change was that initdb and pg_dump would look in the
hard-coded bindir directory if it can't find the requested binary in the
same directory as the caller. The new code throws an error. The old
behavior seemed too error prone for version mismatches.
conversion of basic ASCII letters. Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower. These functions use the same notions of
case folding already developed for identifier case conversion. I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent. Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.

I have updated the pg_dump version so old binary dumps will load fine.
Pre-7.5 dumps use WITHOUT OIDS in SQL were needed, so they should be
fine.

in one query, rather than making a separate query for each object that
could have a comment. This costs relatively little space (a few tens of

third.

object types, rather than by OID. This should help ensure consistent
dump output from databases that are logically the same but have different
histories, per recent discussion about 'diffing' databases. The patch
is bulky because of renaming of fields, but not very complicated.
Also, do some tweaking to cause BLOB restoration to be done in a better
order, and clean up pg_restore's textual output to exactly match pg_dump.

recent discussion. The lexer is used for both SQL command text and
backslash commands. The purpose of this change is to make it easier to
track the behavior of the backend's SQL lexer --- essentially identical
flex rules are now used by psql. Also, this cleans up a lot of very
squirrelly code in mainloop.c and command.c. The flex code is somewhat
bulkier than the removed code, but should be lots easier to maintain.

does. (see

2) Updates both xlog.c and slru.c in backend/access/transam/
3) Also updates pg_resetxlog, which also uses readdir() and checks the
errno value after the loop.

wit: Add a header record to each WAL segment file so that it can be reliably
identified. Avoid splitting WAL records across segment files (this is not
strictly necessary, but makes it simpler to incorporate the header records).
Make WAL entries for file creation, deletion, and truncation (as foreseen but
never implemented by Vadim). Also, add support for making XLOG_SEG_SIZE
configurable at compile time, similarly to BLCKSZ. Fix a couple bugs I
introduced in WAL replay during recent smgr API changes. initdb is forced
due to changes in pg_control contents.
Make btree index creation and initial validation of foreign-key constraints
use maintenance_work_mem rather than work_mem as their memory limit.
Add some code to guc.c to allow these variables to be referenced by their
old names in SHOW and SET commands, for backwards compatibility.

To those who are really interested, and there are a few of you: the attached
patch + file will allow the source base to be compiled (and, for some
definition, "run") under MingW, with the following caveats (I wanted to
first properly fix all but the last of these, but y'all won't quit asking
for a patch :-):
* child death: SIGCHLD not yet sent, so as a minimum, you'll need to
put in some sort of delay after StartupDatabase, and handle setting
StartupPID to 0 etc (ie. the stuff the reaper() signal function is supposed
to do)
* dirmod.c: comment out the elog calls
* dfmgr.c: some hackage required to substitute_libpath_macro
* slru/xact.c: comment out the errno checking after the readdir
(fixed by next version of MingW)
Again, this is only if you *really* want to see postgres compile and start,
and is a nice leg-up for working on the other Win32 TODO list items. Just
don't expect too much else from it at this point...

agreement with what the backend grammar actually accepts (which is a
bit looser than what its documentation claims). Per report from Bill
Moran, though I did not use his patch since it removed all the
undocumented flexibility that the code historically had and the backend
still has.
way to fix this is probably implementing safe memory handling functions
once in a static lib and then using that in the various client apps,
but for the moment I've just reverted the change to un-break the tree.
little more sane. Some parts of the code was using a static function
xmalloc() that did safe memory allocation (where "safe" means "bail
out on OOM"), but most of it was just invoking calloc() or malloc()
