Tom Lane 7762619e95 Replace pg_shadow and pg_group by new role-capable catalogs pg_authid
and pg_auth_members.  There are still many loose ends to finish in this
patch (no documentation, no regression tests, no pg_dump support for
instance).  But I'm going to commit it now anyway so that Alvaro can
make some progress on shared dependencies.  The catalog changes should
be pretty much done.

Neil Conway a159ad3048 Remove support for Kerberos V4. It seems no one is using this, it has
some security issues, and upstream has declared it "dead". Patch from
Magnus Hagander, minor editorialization from Neil Conway.

Tom Lane 943b396245 Add Oracle-compatible GREATEST and LEAST functions. Pavel Stehule 2005-06-26 22:05:42 +00:00
Tom Lane d395aecffa Code review for escape-strings patch. Sync psql and plpgsql lexers
with main, avoid using a SQL-defined SQLSTATE for what is most definitely
not a SQL-compatible error condition, fix documentation omissions,
adhere to message style guidelines, don't use two GUC_REPORT variables
when one is sufficient.  Nothing done about pg_dump issues.

Bruce Momjian bb3cce4ec9 Add E'' syntax so eventually normal strings can treat backslashes
literally.

Add GUC variables:

        "escape_string_warning" - warn about backslashes in non-E strings
        "escape_string_syntax" - supports E'' syntax?
        "standard_compliant_strings" - treats backslashes literally in ''

Update code to use E'' when escapes are used.

Tom Lane fbcbc5d06f Force a checkpoint before committing a CREATE DATABASE command. This
should fix the recent reports of "index is not a btree" failures,
as well as preventing a more obscure race condition involving changes
to a template database just after copying it with CREATE DATABASE.

Tom Lane b90f8f20f0 Extend r-tree operator classes to handle Y-direction tests equivalent
to the existing X-direction tests.  An rtree class now includes 4 actual
2-D tests, 4 1-D X-direction tests, and 4 1-D Y-direction tests.
This involved adding four new Y-direction test operators for each of
box and polygon; I followed the PostGIS project's lead as to the names
of these operators.
NON BACKWARDS COMPATIBLE CHANGE: the poly_overleft (&<) and poly_overright
(&>) operators now have semantics comparable to box_overleft and box_overright.
This is necessary to make r-tree indexes work correctly on polygons.
Also, I changed circle_left and circle_right to agree with box_left and
box_right --- formerly they allowed the boundaries to touch.  This isn't
actually essential given the lack of any r-tree opclass for circles, but
it seems best to sync all the definitions while we are at it.

Tom Lane 4cc7a93d22 Make REINDEX DATABASE do what one would expect, namely reindex all indexes
in the database.  The old behavior (reindex system catalogs only) is now
available as REINDEX SYSTEM.  I did not add the complementary REINDEX USER
case since there did not seem to be consensus for this, but it would be
trivial to add later.  Per recent discussions.

Tom Lane 676bb1ab06 Add a hack requested by the JDBC driver writers: when a function's
argument list contains parameter symbols ($n) declared as type VOID,
discard these arguments.  This allows the driver to avoid renumbering
mixed IN and OUT argument placeholders (the JDBC syntax involves writing
? for both IN and OUT parameters, but on the server side we don't think
that OUT parameters are arguments).  This doesn't break any currently-
useful cases since VOID is not used as an input argument type.

Tom Lane 7a28de2052 pg_dump can now dump large objects even in plain-text output mode, by
using the recently added lo_create() function.  The restore logic in
pg_restore is greatly simplified as well, since there's no need anymore
to try to adjust database references to match a new set of blob OIDs.

Tom Lane 6f7fc0bade Cause initdb to create a third standard database "postgres", which
unlike template0 and template1 does not have any special status in
terms of backend functionality.  However, all external utilities such
as createuser and createdb now connect to "postgres" instead of
template1, and the documentation is changed to encourage people to use
"postgres" instead of template1 as a play area.  This should fix some
longstanding gotchas involving unexpected propagation of database
objects by createdb (when you used template1 without understanding
the implications), as well as ameliorating the problem that CREATE
DATABASE is unhappy if anyone else is connected to template1.
Patch by Dave Page, minor editing by Tom Lane.  All per recent
pghackers discussions.

Neil Conway 577247b023 Minor documentation update for RAISE expression patch. 2005-06-19 23:39:05 +00:00
Tom Lane a8d1075f27 Add a time-of-preparation column to the pg_prepared_xacts view, per an
old suggestion by Oliver Jowett.  Also, add a transaction column to the
pg_locks view to show the xid of each transaction holding or awaiting
locks; this allows prepared transactions to be properly associated with
the locks they own.  There was already a column named 'transaction',
and I chose to rename it to 'transactionid' --- since this column is
new in the current devel cycle there should be no backwards compatibility
issue to worry about.

Neil Conway 4aaff55359 Minor SGML markup cleanup. 2005-06-15 06:29:25 +00:00
Bruce Momjian 0851a6fbc7 This patch makes it possible to use the full set of timezones when doing
"AT TIME ZONE", and not just the shorlist previously available. For
example:

SELECT CURRENT_TIMESTAMP AT TIME ZONE 'Europe/London';

works fine now. It will also obey whatever DST rules were in effect at
just that date, which the previous implementation did not.

It also supports the AT TIME ZONE on the timetz datatype. The whole
handling of DST is a bit bogus there, so I chose to make it use whatever
DST rules are in effect at the time of executig the query. not sure if
anybody is actuallyi *using* timetz though, it seems pretty
unpredictable just because of this...

Neil Conway d6636543c4 Allow the parameters to PL/PgSQL's RAISE statement to be expressions,
instead of just scalar variables. Add regression tests and update the

Tom Lane c186c93148 Change the planner to allow indexscan qualification clauses to use
nonconsecutive columns of a multicolumn index, as per discussion around
mid-May (pghackers thread "Best way to scan on-disk bitmaps").  This
turns out to require only minimal changes in btree, and so far as I can
see none at all in GiST.  btcostestimate did need some work, but its
original assumption that index selectivity == heap selectivity was
quite bogus even before this.
2005-06-13 23:14:49 +00:00
Neil Conway 077811605e Per discussion on -hackers, this patch changes psql's "expanded" output
mode to only affect the presentation of normal query results, not the
output of psql slash commands. Documentation updated. I also made
some unrelated minor psql cleanup. Per suggestion from Stuart Cooper.

Neil Conway 8c05ca7754 SGML cleanup: consistently use "endterm" in <xref>s that link to the

2005-06-13 02:40:08 +00:00
Tom Lane a2fb7b8a1f Adjust lo_open() so that specifying INV_READ without INV_WRITE creates
a descriptor that uses the current transaction snapshot, rather than
SnapshotNow as it did before (and still does if INV_WRITE is set).
This means pg_dump will now dump a consistent snapshot of large object
contents, as it never could do before.  Also, add a lo_create() function
that is similar to lo_creat() but allows the desired OID of the large
object to be specified.  This will simplify pg_restore considerably
(but I'll fix that in a separate commit).

Neil Conway 72a5db15d1 libpq was not consistently checking for memory allocation failures. This
patch adds missing checks to the call sites of malloc(), strdup(),

PQmakeEmptyPGresult() not checking for malloc() failure.

Neil Conway a89c109e30 Minor cleanup of documentation for recently-added HISTFILE psql variable. 2005-06-10 16:26:59 +00:00
Neil Conway d46bc444ac Implement two new special variables in PL/PgSQL: SQLSTATE and SQLERRM.
These contain the SQLSTATE and error message of the current exception,
respectively. They are scope-local variables that are only defined
in exception handlers (so attempting to reference them outside an
exception handler is an error). Update the regression tests and the
documentation.

Also, do some minor related cleanup: export an unpack_sql_state()
function from the backend and use it to unpack a SQLSTATE into a
string, and add a free_var() function to pl_exec.c

Original patch from Pavel Stehule, review by Neil Conway.
2005-06-10 16:23:11 +00:00
Bruce Momjian ea88824a3e the following patch makes the filename used to store the readline
history customizable through a variable named HISTFILE, analogous to
psql's already implemented HISTCONTROL and HISTSIZE variables, and
bash's HISTFILE-Variable.

The motivation was to be able to get psql to maintain separate
histories for separate databases.  This is now easily achievable
through a line like the following in ~/.psqlrc:

\set HISTFILE ~/.psql_history-:DBNAME

Bruce Momjian ebc8649892 Since I needed this feature badly, I added the -n / --schema switch to
pg_restore. It restores the given schemaname only. It can be used in

fine grained.

Bruce Momjian 4a5cda7bba I've created a patch which adds support for troff "-ms" output to
psql.  i.e. "\pset format troff-ms".  The patch also corrects some
problems with the "latex" format, notably defining an extra column in
the output table, and correcting some alignment issues; it also
changes the output to match the border setting as documented in the
manual page and as shown with the "aligned" format.

The troff-ms output is mostly identical to the latex output allowing
for the differences between the two typesetters.

The output should be saved in a file and piped as follows:

  cat file | tbl | troff -T ps -ms > file.ps
or
  tbl file | troff -T ps -ms > file.ps

Because it contains tabs, you'll need to redirect psql output or use
"script", rather than pasting from a terminal window, due to the tabs
which can be replaced with spaces.

Tom Lane 77c168a836 Remove grammar productions for prefix and postfix % and ^ operators,
as well as the existing pg_catalog entries for prefix and postfix %.
These have never been documented, though they did appear in one old
regression test.  This avoids surprising behavior in cases like
"SELECT -25 % -10".  Per recent discussion.
Note: although there is a catalog change here, I did not force initdb
since there's no harm in leaving the inaccessible entries in one's
copy of pg_operator.

Tom Lane f5b2f60bd1 Change WAL-logging scheme for multixacts to be more like regular
transaction IDs, rather than like subtrans; in particular, the information
now survives a database restart.  Per previous discussion, this is
essential for PITR log shipping and for 2PC.
