Bruce Momjian 070a3ad76b Rename pg_stat_file columns to be more consistent. Split apart change
and creation columns to behave for Unix or Win32.
2005-08-15 23:00:14 +00:00
Tom Lane 2af9a44fa9 Make pg_stat_file() use OUT parameters so that the user doesn't have to
remember the output parameter set for himself.  It's a bit of a kluge
but fixing array_in to work in bootstrap mode looks worse.
I removed the separate pg_file_length() function, as it no longer has any
real notational advantage --- you can write (pg_stat_file(...)).length.

Tom Lane a43ea120bf Code & docs review for server instrumentation patch. File timestamps
should surely be timestamptz not timestamp; fix some but not all of the
holes in check_and_make_absolute(); other minor cleanup.  Also put in
the missed catversion bump.

place.

Bruce Momjian b2b6548c79 Please find attached diffs for documentation and simple regression
tests for the new interval->day changes. I added tests for
justify_hours() and justify_days() to interval.sql, as they take
interval input and produce interval output. If there's a more
appropriate place for them, please let me know.

Remove /contrib/dbsize.

Tom Lane af019fb9ae Add a role property 'rolinherit' which, when false, denotes that the role
doesn't automatically inherit the privileges of roles it is a member of;
for such a role, membership in another role can be exploited only by doing
explicit SET ROLE.  The default inherit setting is TRUE, so by default
the behavior doesn't change, but creating a user with NOINHERIT gives closer
adherence to our current reading of SQL99.  Documentation still lacking,
and I think the information schema needs another look.
2005-07-26 16:38:29 +00:00
Tom Lane f9fd176461 Add pg_has_role() family of privilege inquiry functions modeled after the
existing ones for object privileges.  Update the information_schema for
roles --- pg_has_role() makes this a whole lot easier, removing the need
for most of the explicit joins with pg_user.  The views should be a tad
faster now, too.  Stephen Frost and Tom Lane.
2005-07-26 00:04:19 +00:00
Tom Lane e5d6b91220 Add SET ROLE. This is a partial commit of Stephen Frost's recent patch;
I'm still working on the has_role function and information_schema changes.

Bruce Momjian 261026575d Fix AT TIME ZONE for timestamps without time zones:
test=> select ('2005-07-20 00:00:00'::timestamp without time zone) at
	time zone 'Europe/Paris';
	        timezone
	------------------------
	 2005-07-19 22:00:00-04

Udpate documentation.
2005-07-22 21:16:15 +00:00
Bruce Momjian db05f4a7eb Add 'day' field to INTERVAL so 1 day interval can be distinguished from
24 hours. This is very helpful for daylight savings time:

	select '2005-05-03 00:00:00 EST'::timestamp with time zone + '24 hours';
	      ?column?
	----------------------
	2005-05-04 01:00:00-04

	select '2005-05-03 00:00:00 EST'::timestamp with time zone + '1 day';
	      ?column?
	----------------------

Tom Lane 37464a0326 Fix some bogosities in geometric-function documentation: add an entry
for circle(polygon), which was missing; remove bogus entry for
point(lseg, lseg), which does not exist, and the documentation seemed to
describe lseg_interpt, which we already document as an operator not a
function.  Also remove entry for box_intersect, which likewise is
preferentially used via the operator #.

Neil Conway c3f1b0f4dd This doc patch replaces all inappropriate references to SQL:1999 when it
is used as if it were the latest (and/or still valid) SQL standard.
SQL:2003 is used in its place. Patch from Simon Riggs.

Bruce Momjian 75a64eeb4b I made the patch that implements regexp_replace again.
The specification of this function is as follows.

regexp_replace(source text, pattern text, replacement text, [flags
text])
returns text

Replace string that matches to regular expression in source text to
replacement text.

 - pattern is regular expression pattern.
 - replacement is replace string that can use '\1'-'\9', and '\&'.
    '\1'-'\9': back reference to the n'th subexpression.
    '\&'     : entire matched string.
 - flags can use the following values:
    g: global (replace all)
    i: ignore case
    When the flags is not specified, case sensitive, replace the first
    instance only.

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.

Tom Lane 943b396245 Add Oracle-compatible GREATEST and LEAST functions. Pavel Stehule 2005-06-26 22:05:42 +00:00
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.

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...

Bruce Momjian 4d0e7b4aac Please find attached a patch (diff -c against cvs HEAD) to add a
function that accepts a double precision argument assumed to be a Unix
epoch timestamp and returns timestamp with time zone, and accompanying
documentation.

Usage:

test=# select to_timestamp(200120400);
       to_timestamp
