While we normally prefer the notation "foo.*" for a whole-row Var, that does
not work at SELECT top level, because in that context the parser will assume
that what is wanted is to expand the "*" into a list of separate target
columns, yielding behavior different from a whole-row Var. We have to emit
just "foo" instead in that context. Per report from Sokolov Yura.

discarded by cache flush while still in use. This is a minimal patch that
just copies the tupdesc anywhere it could be needed across a flush. Applied
to back branches only; Neil Conway is working on a better long-term solution
for HEAD.

Back-patch of previous fix in HEAD for plperl-vs-locale issue.

selection of a field from the result of a function returning RECORD.
I believe this case is new in 8.1; it's due to the addition of OUT parameters.
Per example from Michael Fuhr.

equal: if strcoll claims two strings are equal, check it with strcmp, and
sort according to strcmp if not identical. This fixes inconsistent
behavior under glibc's hu_HU locale, and probably under some other locales
as well. Also, take advantage of the now-well-defined behavior to speed up
texteq, textne, bpchareq, bpcharne: they may as well just do a bitwise
comparison and not bother with strcoll at all.
NOTE: affected databases may need to REINDEX indexes on text columns to be
sure they are self-consistent.

that simplify_boolean_equality() may leave behind. This is only relevant
if the user writes something a bit silly, like CASE x=y WHEN TRUE THEN.
Per example from Michael Fuhr; may or may not explain bug #2106.

Map them to a single day, so '30 hours' is 'AM'.
Have to_char(interval) and to_char(time) use "HH", "HH12" as 12-hour
intervals, rather than bypass and print the full interval hours. This
is neeeded because to_char(time) is mapped to interval in this function.
Intervals should use "HH24", and document suggestion.
Allow "D" format specifiers for interval/time.

change errno. No reported bugs here, but why take a chance?
|
|
comment line where output as too long, and update typedefs for /lib
directory. Also fix case where identifiers were used as variable names
in the backend, but as typedefs in ecpg (favor the backend for
indenting).
Backpatch to 8.1.X.

create circularity of role memberships. This is a minimum-impact fix
for the problem reported by Florian Pflug. I thought about removing
the superuser_arg test from is_member_of_role() altogether, as it seems
redundant for many of the callers --- but not all, and it's way too late
in the 8.1 cycle to be making large changes. Perhaps reconsider this
later.

interval_justify_hours in timestamp subtraction. TODO already has text
description.
|
|
some small stylistic improvements in these functions. Also fix several
places where TMODULO() was being used with wrong-sized quotient argument,
creating a risk of overflow --- interval2tm was actually capable of going
into an infinite loop because of this.
|
|
gettimeofday with NULL in a few places, making it consistent with
usage elsewhere.
|
|
Per gripe from Chris Matheson.
|
|
fix problems with replacement-string backslashes that aren't followed by
one of the expected characters, avoid giving the impression that
replace_text_regexp() is meant to be called directly as a SQL function,
etc.
|
|
exported routines of ip.c, md5.c, and fe-auth.c to begin with 'pg_'.
Also get rid of the vestigial fe_setauthsvc/fe_getauthsvc routines
altogether.

regression=# select '23:59:59.9'::time(0);
time
----------
24:00:00
(1 row)
This is bad because:
regression=# select '24:00:00'::time(0);
ERROR: date/time field value out of range: "24:00:00"
The last example now works.

valid type information if they are asked to fetch the values part of a
pg_statistic slot; these arguments are unneeded if fetching only the
numbers part. Use this to save a catcache lookup in btcostestimate,
which is looking like a bit of a hotspot in recent profiling. Not a
big savings, but since it's essentially free, might as well do it.

traceable to grant options. As per my earlier proposal, a GRANT made by
a role member has to be recorded as being granted by the role that actually
holds the grant option, and not the member.

like '23:59:60' because of fractional-second roundoff problems. Trying
to control this upstream of the actual display code was hopeless; the right
way is to explicitly round fractional seconds in the display code and then
refigure the results if the fraction rounds up to 1. Per bug #1927.

testing ownership if the caller isn't interested in any GOPTION bits
(which is the common case). It did not matter in 8.0 where the ownership
test was just a trivial equality test, but it matters now.
|
|
the parameter's name (if any) as the default column name for SELECT FROM
the function, rather than the function name as previously. I still think
this is a bad idea, but I lost the argument. Force decompilation of
function RTEs to specify full aliases always, to reduce the odds of this
decision breaking dumped views.

argument as a 'regclass' value instead of a text string. The frontend
conversion of text string to pg_class OID is now encapsulated as an
implicitly-invocable coercion from text to regclass. This provides
backwards compatibility to the old behavior when the sequence argument
is explicitly typed as 'text'. When the argument is just an unadorned
literal string, it will be taken as 'regclass', which means that the
stored representation will be an OID. This solves longstanding problems
with renaming sequences that are referenced in default expressions, as
well as new-in-8.1 problems with renaming such sequences' schemas or
moving them to another schema. All per recent discussion.
Along the way, fix some rather serious problems in dbmirror's support
for mirroring sequence operations (int4 vs int8 confusion for instance).

Also, make pg_total_relation_size include the size of the
TOAST index.

|
sake of brevity and clarity.
Make pg_reload_conf(), pg_rotate_logfile(), and pg_cancel_backend()
return a boolean rather than an integer to indicate success or failure.
Along the way, make some minor cleanups to dbsize.c -- in particular,
use elog() rather than ereport() for "shouldn't happen" error
conditions, and remove some of the more flagrant violations of the
Postgres indentation conventions.
Catalog version bumped.

is a non-finite timestamp, for consistency with related functions.
In other words: +infinity rotated to a different timezone is still
+infinity.

in the zic database or zone names found in the date token table. This
preserves the old ability to do AT TIME ZONE 'PST' along with the new
ability to do AT TIME ZONE 'PST8PDT'. Per gripe from Bricklen Anderson.
Also, fix some inconsistencies in usage of TZ_STRLEN_MAX --- the old
code had the potential for one-byte buffer overruns, though given
alignment considerations it's unlikely there was any real risk.

it can be done right. Allow explicit use of absolute DataDir path.

in interval_mul and interval_div. This avoids an optimization bug
in A Certain Company's compiler (and given their explanation, I wouldn't
be surprised if other compilers blow it too). Besides the code seems
more clear this way --- in the original formulation, you had to mentally
recognize the common subexpression in order to understand what was going
on.

Fix to_char(interval) to return large year/month/day/hour values that
are larger than possible timestamp values.
Prevent to_char(interval) format specifications that make no sense, like
Month.
Clean up formatting.c code to more logically handle return lengths.

their OID parameter. It was possible to crash the backend with
select array_in('{123}',0,0); because that would bypass the needed step
of initializing the workspace. These seem to be the only two places
with a problem, though (record_in and record_recv don't have the issue,
and the other array functions aren't depending on user-supplied input).
Back-patch as far as 7.4; 7.3 does not have the bug.
