Tom Lane 15c194c1d5 Add GUC parameter check_function_bodies to control whether validation
of function bodies is done at CREATE FUNCTION time.  This is normally
true but can be set false to avoid problems with forward references,
wrong schema search path, etc.  This is just the backend patch, still
need to adjust pg_dump to make use of it.

Tom Lane 19c90bcc25 Add a bit more locking to vac_update_relstats and vac_update_dbstats
to make them comparable to what UpdateStats does in the same situation.
I'm not certain two instances of vac_update_relstats could run in
parallel for the same relation, but parallel invocations of vac_update_dbstats
do seem possible.

Tom Lane bea8af9152 When dumping CREATE INDEX, must show opclass name if the opclass isn't
in the schema search path.  Otherwise pg_dump doesn't correctly dump
scenarios where a custom opclass is created in 'public' and then used
by indexes in other schemas.

Tom Lane 55d85f42a8 Repair RI trigger visibility problems (this time for sure ;-)) per recent
discussion on pgsql-hackers: in READ COMMITTED mode we just have to force
a QuerySnapshot update in the trigger, but in SERIALIZABLE mode we have
to run the scan under a current snapshot and then complain if any rows
would be updated/deleted that are not visible in the transaction snapshot.

Tom Lane e33f205a94 Adjust btree index build procedure so that the btree metapage looks
invalid (has the wrong magic number) until the build is entirely
complete.  This turns out to cost no additional writes in the normal
case, since we were rewriting the metapage at the end of the process
anyway.  In normal scenarios there's no real gain in security, because
a failed index build would roll back the transaction leaving an unused
index file, but for rebuilding shared system indexes this seems to add
some useful protection.

Bruce Momjian 2f98ece4de The brackets aren't put on the CHECK constraints properly.
Before patch:

test=# select pg_get_constraintdef(oid) from pg_constraint;
                                       pg_get_constraintdef
-------------------------------------------------------------------------------------------------
  CHECK (VALUE >= 0)
  CHECK ((((a)::text = 'asdf'::text) OR ((a)::text = 'fdsa'::text)) OR
((a)::text = 'dfd'::text))
  PRIMARY KEY (b)
  FOREIGN KEY (a) REFERENCES test2(b)
  UNIQUE (b)
(5 rows)

test=# select pg_get_constraintdef(oid, true) from pg_constraint;
                                pg_get_constraintdef
-----------------------------------------------------------------------------------
  CHECK VALUE >= 0
  CHECK a::text = 'asdf'::text OR a::text = 'fdsa'::text OR a::text =
'dfd'::text
  PRIMARY KEY (b)
  FOREIGN KEY (a) REFERENCES test2(b)
  UNIQUE (b)
(5 rows)

After patch:

test=# select pg_get_constraintdef(oid) from pg_constraint;
                                       pg_get_constraintdef
-------------------------------------------------------------------------------------------------
  CHECK (VALUE >= 0)
  CHECK ((((a)::text = 'asdf'::text) OR ((a)::text = 'fdsa'::text)) OR
((a)::text = 'dfd'::text))
  PRIMARY KEY (b)
  FOREIGN KEY (a) REFERENCES test2(b)
  UNIQUE (b)
(5 rows)

test=# select pg_get_constraintdef(oid, true) from pg_constraint;
                                pg_get_constraintdef
-----------------------------------------------------------------------------------
  CHECK (VALUE >= 0)

`  CHECK (a::text = 'asdf'::text OR a::text = 'fdsa'::text OR a::text =
'dfd'::text)
  PRIMARY KEY (b)
  FOREIGN KEY (a) REFERENCES test2(b)
  UNIQUE (b)
(5 rows)

It's important that those brackets are there to (a) match all other
constraints and (b) so that people can just copy and paste them and it
will work as SQL.

Tom Lane 8934790052 Add a mechanism to let dynamically loaded modules register post-commit/

for other dynamically loaded modules seems obvious.

Tom Lane a15207f8d6 Now that we have UPDATE tab SET col = DEFAULT, get rid of horrid hack
in the RI triggers for ON DELETE/UPDATE SET DEFAULT.  The code depended
way too much on knowledge of plan structure, and yet still would fail
if the generated query got rewritten by rules.

Peter Eisentraut e05147e51a You can't NLS-enable a program component by just putting gettext() around

Tom Lane a56a016ceb Repair some REINDEX problems per recent discussions. The relcache is
now able to cope with assigning new relfilenode values to nailed-in-cache
indexes, so they can be reindexed using the fully crash-safe method.  This
leaves only shared system indexes as special cases.  Remove the 'index
deactivation' code, since it provides no useful protection in the shared-
index case.  Require reindexing of shared indexes to be done in standalone
mode, but remove other restrictions on REINDEX.  -P (IgnoreSystemIndexes)
now prevents using indexes for lookups, but does not disable index updates.
It is therefore safe to allow from PGOPTIONS.  Upshot: reindexing system catalogs
can be done without a standalone backend for all cases except
shared catalogs.
2003-09-24 18:54:02 +00:00
Tom Lane dbf8259adf Tweak generic_type_consistency routines to avoid loss of functionality
since 7.3: 'select array_dims(histogram_bounds) from pg_stats' used to
work and still should.  Problem was that code wouldn't take input of
declared type anyarray as matching an anyarray argument.  Allow this
case as long as we don't need to determine an element type (which in
practice means as long as anyelement isn't used in the function signature).

Tom Lane f03d2284c0 HeapTupleSatisfiesVacuum() needs to be more careful about the

tuples inserted and then deleted by a concurrent transaction.
Example of bug:

CREATE TABLE
regression=# begin;
BEGIN
regression=# insert into foo values(1);
INSERT 195531 1
regression=# delete from foo;
DELETE 1
regression=# insert into foo values(1);
INSERT 195532 1

Tom Lane 5aa29e88e9 Arrange to align shared disk buffers on at least 32-byte boundaries,
not just MAXALIGN boundaries.  This makes a noticeable difference in
the speed of transfers to and from kernel space, at least on recent
Pentiums, and might help other CPUs too.  We should look at making
this happen for local buffers and buffile.c too.  Patch from Manfred Spraul.

Tom Lane a13b018530 Disallow foreign-key references from temp tables to permanent tables.
Per recent discussion, this does not work because other backends can't
reliably see tuples in a temp table and so cannot run the RI checks
correctly.  Seems better to disallow this case than go back to accessing
temp tables through shared buffers.  Also, disallow FK references to
ON COMMIT DELETE ROWS tables.  We already caught this problem for normal
TRUNCATE, but the path used by ON COMMIT didn't check.
2003-09-19 21:04:20 +00:00
Tom Lane 28847ae77d Seems like a bad idea that REINDEX TABLE supports (or thinks it does)
reindexing system tables without ignoring system indexes, when the
other two varieties of REINDEX disallow it.  Make all three act the same,
and simplify downstream code accordingly.
2003-09-19 19:57:42 +00:00
Tom Lane 6b73da67b2 Disallow converting a table to a view if it has triggers, indexes, or

of views.  Per bug report from Chris Pizzi.

2003-09-16 00:50:09 +00:00
Tom Lane db18703b5a Fix LISTEN/NOTIFY race condition reported by Gavin Sherry. While a
really general fix might be difficult, I believe the only case where
AtCommit_Notify could see an uncommitted tuple is where the other guy
has just unlistened and not yet committed.  The best solution seems to
be to just skip updating that tuple, on the assumption that the other
guy does not want to hear about the notification anyway.  This is not
perfect --- if the other guy rolls back his unlisten instead of committing,
then he really should have gotten this notify.  But to do that, we'd have
to wait to see if he commits or not, or make UNLISTEN hold exclusive lock
on pg_listener until commit.  Either of these answers is deadlock-prone,
not to mention horrible for interactive performance.  Do it this way
for now.  (What happened to that project to do LISTEN/NOTIFY in memory
with no table, anyway?)

Tom Lane 94a13b8a11 Okay, I've had it with mktime() bugs. While chasing Torello Querci's
recent gripe, I discovered not one but two undocumented, undesirable
behaviors of glibc's mktime.  So, stop using it entirely, and always
rely on inversion of localtime() to determine the local time zone.
It's not even very much slower, as it turns out that mktime (at least
in the glibc implementation) also does repeated reverse-conversions.

Tom Lane 8b43e325eb Revert to our pre-7.4 behavior of identifying Unix-socket connections in

Tom Lane b1d3de6b96 Someone (possibly me) foolishly reduced the response for failing

Tom Lane 48beecda7c Remove geqo_random_seed parameter. Having geqo reset the global random()

Tom Lane 5ac2d7c0eb In _bt_check_unique() loop, don't bother applying _bt_isequal() to
killed items; just skip to the next item immediately.  Only check for
key equality when we reach a non-killed item or the end of the index
page.  This saves key comparisons when there are lots of killed items,
as for example in a heavily-updated table that's not been vacuumed lately.
Seems to be a win for pgbench anyway.

Tom Lane b916cc435a Cause standalone backend (including bootstrap case) to read the GUC
config file if it exists.  This was already discussed as being a good
idea, and now seems the cleanest way to deal with initdb-time failures
on machines with small SHMMAX.  (The submitted patches instead modified
initdb.sh to pass the correct sizing parameters, but that would still
leave standalone backends prone to failure later.  An admin who needs
to use a standalone backend has enough trouble already, he shouldn't
have to manually configure its shmem settings...)

Tom Lane 65c2d427fb Preliminary cleanup for hash index code (doesn't attack the locking problem
yet).  Fix a couple of bugs that would only appear if multiple bitmap pages
are used, including a buffer reference leak and incorrect computation of bit
indexes.  Get rid of 'overflow address' concept, which accomplished nothing
except obfuscating the code and creating a risk of failure due to limited
range of offset field.  Rename some misleadingly-named fields and routines,
and improve documentation.

Tom Lane 92ee2528d8 Tweak processing of multiple-index-scan plans to reduce overhead when

Tom Lane 80860c32d9 Improve dynahash.c's API so that caller can specify the comparison function
as well as the hash function (formerly the comparison function was hardwired
as memcmp()).  This makes it possible to eliminate the special-purpose
hashtable management code in execGrouping.c in favor of using dynahash to
manage tuple hashtables; which is a win because dynahash knows how to expand
a hashtable when the original size estimate was too small, whereas the
special-purpose code was too stupid to do that.  (See recent gripe from
Stephan Szabo about poor performance when hash table size estimate is way
off.)  Free side benefit: when using string_hash, the default comparison
function is now strncmp() instead of memcmp().  This should eliminate some
part of the overhead associated with larger NAMEDATALEN values.

routines also use the cache.  Change the operator search algorithms to look
for appropriate btree or hash index opclasses, instead of assuming operators
named '<' or '=' have the right semantics.  (ORDER BY ASC/DESC now also look
at opclasses, instead of assuming '<' and '>' are the right things.)  Add

By the way: The "virtual_host" parameter is a bad name for that
particular option, I think. "Virtual host" signals that PostgreSQL will
behave differently according to which IP address it's contacted (like
Apache's virtual host support which makes the web-server serve different
sites according to different criteria). A better word for the options
would be "tcpip_listen_addr" or something like that.

Tom Lane c01641f8ae libpq failed to cope with COPY FROM STDIN if the command was issued
via extended query protocol, because it sends Sync right after Execute
without realizing that the command to be executed is COPY.  There seems
to be no reasonable way for it to realize that, either, so the best fix
seems to be to make the backend ignore Sync during copy-in mode.  Bit of
a wart on the protocol, but little alternative.  Also, libpq must send
another Sync after terminating the COPY, if the command was issued via
Execute.

index pages: when _bt_getbuf asks the FSM for a free index page, it is

be problematic.  Fix by doing a conditional rather than unconditional

I'd have to disagree with regards to the memory leaks not being worth
a mention - any such leak can cause problems when the PostgreSQL
installation is either unattended, long-living andor has very high
connection levels. Half a kilobyte on start-up isn't negligible in
this light.

In the first case, enable_seqscan is set to its default value. After
setting it to off, it is obvious that the value has been changed for the
session only. In the third case, you can see that the value has been set
specifically for the user.

Bruce Momjian 397831e103 At long last I put together a patch to support 4 client SSL negotiation
modes (and replace the requiressl boolean). The four options were first
spelled out by Magnus Hagander <mha@sollentuna.net> on 2000-08-23 in email
to pgsql-hackers, archived here:

http://archives.postgresql.org/pgsql-hackers/2000-08/msg00639.php

My original less-flexible patch and the ensuing thread are archived at:

http://dbforums.com/t623845.html

Attached is a new patch, including documentation.

To sum up, there's a new client parameter "sslmode" and environment
variable "PGSSLMODE", with these options:

sslmode   description
-------   -----------
disable   Unencrypted non-SSL only
allow     Negotiate, prefer non-SSL
prefer    Negotiate, prefer SSL (default)
require   Require SSL

The only change to the server is a new pg_hba.conf line type,
"hostnossl", for specifying connections that are not allowed to use SSL
(for example, to prevent servers on a local network from accidentally
using SSL and wasting cycles). Thus the 3 pg_hba.conf line types are:

pg_hba.conf line types
----------------------
host       applies to either SSL or regular connections
hostssl    applies only to SSL connections
hostnossl  applies only to regular connections

These client and server options, the postgresql.conf ssl = false option,
and finally the possibility of compiling with no SSL support at all,
make quite a range of combinations to test. I threw together a test
script to try many of them out. It's in a separate tarball with its
config files, a patch to psql so it'll announce SSL connections even in
absence of a tty, and the test output. The test is especially informative
when run on the same tty the postmaster was started on, so the FATAL:
errors during negotiation are interleaved with the psql client output.

I saw Tom write that new submissions for 7.4 have to be in before midnight
local time, and since I'm on the east coast in the US, this just makes it
in before the bell. :)

Tom Lane 9117e55493 Tweak original coding so that we can determine the platform-specific

by making the hardwired defaults tiny, perhaps, but why slow down
bootstrap by starving it for buffers...)

Tom Lane de98a7e23a The default values for shared_buffers and max_connections are now 1000
and 100 respectively, if the platform will allow it.  initdb selects
values that are not too large to allow the postmaster to start, and
places these values in the installed postgresql.conf file.  This allows
us to continue to start up out-of-the-box on platforms with small SHMMAX,
while having somewhat-realistic default settings on platforms with
reasonable SHMMAX.  Per recent pghackers discussion.

Tom Lane 835bb975d8 Restructure building of join relation targetlists so that a join plan
node emits only those vars that are actually needed above it in the
plan tree.  (There were comments in the code suggesting that this was
done at some point in the dim past, but for a long time we have just
made join nodes emit everything that either input emitted.)  Aside from
being marginally more efficient, this fixes the problem noted by Peter
Eisentraut where a join above an IN-implemented-as-join might fail,
because the subplan targetlist constructed in the latter case didn't
meet the expectation of including everything.
Along the way, fix some places that were O(N^2) in the targetlist
length.  This is not all the trouble spots for wide queries by any
means, but it's a step forward.
