* Fix the problem of GRANTs creating "dangling" privileges not directlyTom Lane2005-10-10
| | | | | | 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.
* Fix (hopefully for the last time) problems with datetime values displayingTom Lane2005-10-09
| | | | | | | 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.
* Fix up grammar in variable description string.Tom Lane2005-10-08

* Fix Kerberos authentication in wake of virtual-hosts changes --- needTom Lane2005-10-08
| | | | | | | to call krb5_sname_to_principal() always. Also, use krb_srvname rather than the hardwired string 'postgres' as the appl_version string in the krb5_sendauth/recvauth calls, to avoid breaking compatibility with PG 8.0. Magnus Hagander
* Marginal performance improvement in aclmask(): don't bother withTom Lane2005-10-07
| | | | | | 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.
* When a function not returning RECORD has a single OUT parameter, useTom Lane2005-10-06
| | | | | | | | 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.
* Add a trace_sort option to help with measuring resource usage of externalTom Lane2005-10-03
| | | | sort operations. Per recent discussion. Simon Riggs and Tom Lane.
* Separate out the VacRUsage stuff as an independent module, in preparationTom Lane2005-10-03
| | | | for using it for other things besides VACUUM.
* Change nextval and other sequence functions to specify their sequenceTom Lane2005-10-02
| | | | | | | | | | | | | | | 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).
* Fix confusion between relfilenode and Oid.Alvaro Herrera2005-09-29
| | | | | Also, make pg_total_relation_size include the size of the TOAST index.
* Clean up possibly-uninitialized-variable warnings reported by gcc 4.x.Tom Lane2005-09-24
|
* Suppress signed-vs-unsigned-char warnings.Tom Lane2005-09-24
|
* Fix typo in comment.Tom Lane2005-09-23
|
* Fix postgresql.conf lexer to accept doubled single quotes in literalTom Lane2005-09-21
| | | | | | strings. This is consistent with SQL conventions, and since Bruce already changed initdb in a way that assumed it worked like this, seems we'd better make it work like this.
* autovacuum setting false -> off, for consistencyBruce Momjian2005-09-20
|
* Rename pg_complete_relation_size() to pg_total_relation_size(), for theNeil Conway2005-09-16
| | | | | | | | | | | | | | 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.
* Update two comments to refer to use the new list API names.Neil Conway2005-09-16
|
* Tweak TCP-keepalive code so that an invalid setting doesn't cause usTom Lane2005-09-12
| | | | | | | to drop connections unceremoniously. Also some other marginal cleanups: don't query getsockopt() repeatedly if it fails, and avoid having the apparent definition of struct Port depend on which system headers you might have included or not. Oliver Jowett and Tom Lane.
* timestamptz_izone should return the input, not NULL, when the inputTom Lane2005-09-09
| | | | | | is a non-finite timestamp, for consistency with related functions. In other words: +infinity rotated to a different timezone is still +infinity.
* Fix the various forms of AT TIME ZONE to accept either timezones foundTom Lane2005-09-09
| | | | | | | | | 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.
* Fix the spelling.Tom Lane2005-09-02

* Update listen_addresses description.Bruce Momjian2005-09-02

* Short-circuit AllocSetReset if nothing has been palloc'd in the memoryTom Lane2005-09-01
| | | | | context since the previous AllocSetReset. Original patch by Atsushi Ogawa, editorialized on a little bit by Tom Lane.
* Update documentation about shared memory sizing to reflect currentTom Lane2005-08-30
| | | | reality.
* Reduce default value of max_prepared_transactions from 50 to 5. ThisTom Lane2005-08-29
| | | | | | | | | saves nearly 700kB in the default shared memory segment size, which seems worthwhile, and it is a feature that many users won't use anyway. Per Heikki's argument, there is no point in a compromise value --- those who are using 2PC at all will probably want it at least equal to max_connections. But we can't set it to zero by default without breaking the prepared_xacts regression test.
* Fix platform-specific test for path prefix-ness: move it into path.c whereTom Lane2005-08-29
| | | | | it can be done right. Allow explicit use of absolute DataDir path. Per Dave Page.
* The idea of using _strncoll() on Windows doesn't work. Revert to sameTom Lane2005-08-26
| | | | code as we use on other platforms when encoding is not UTF8.
* Arrange for indexes and toast tables to inherit their ownership fromTom Lane2005-08-26
| | | | | | the parent table, even if the command that creates them is executed by someone else (such as a superuser or a member of the owning role). Per gripe from Michael Fuhr.
* Factor out the common subexpression month_remainder * DAYS_PER_MONTHTom Lane2005-08-25
| | | | | | | | | 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.
* Back out pfrees for justify_hour function calls.Bruce Momjian2005-08-25

* Fix memory leak when using justify_hours.Bruce Momjian2005-08-25
|
* Add small hack to support use of Unicode-based locales on WIN32. ThisTom Lane2005-08-24
| | | | | is not adequately tested yet, but let's get it into beta1 so it can be tested. Magnus Hagander and Tom Lane.
* enable_constraint_exclusion => constraint_exclusionBruce Momjian2005-08-22
| | | | Also improve wording.
* Minor GUC cleanups: document krb_server_hostname and custom_variable_classesTom Lane2005-08-21
| | | | | | in postgresql.conf.sample, mark custom_variable_classes as SIGHUP not POSTMASTER to agree with the documentation (I can't see a reason it has to be POSTMASTER so I think the docs are right).
* Convert the arithmetic for shared memory size calculation from 'int'Tom Lane2005-08-20
| | | | | | | | | | | to 'Size' (that is, size_t), and install overflow detection checks in it. This allows us to remove the former arbitrary restrictions on NBuffers etc. It won't make any difference in a 32-bit machine, but in a 64-bit machine you could theoretically have terabytes of shared buffers. (How efficiently we could manage 'em remains to be seen.) Similarly, num_temp_buffers, work_mem, and maintenance_work_mem can be set above 2Gb on a 64-bit machine. Original patch from Koichi Suzuki, additional work by moi.
* Repair problems with VACUUM destroying t_ctid chains too soon, and withTom Lane2005-08-20
| | | | | | | | | | | | insufficient paranoia in code that follows t_ctid links. (We must do both because even with VACUUM doing it properly, the intermediate state with a dangling t_ctid link is visible concurrently during lazy VACUUM, and could be seen afterwards if either type of VACUUM crashes partway through.) Also try to improve documentation about what's going on. Patch is a bit bulky because passing the XMAX information around required changing the APIs of some low-level heapam.c routines, but it's not conceptually very complicated. Per trouble report from Teodor and subsequent analysis. This needs to be back-patched, but I'll do that after 8.1 beta is out.
* Fix LRU/ALL description mismatch for GUC parameter.Bruce Momjian2005-08-19

* Consistently align comments in postgresql.conf, move some slightly toBruce Momjian2005-08-19
| | | | the right to stand out.
* Add hint for to_char(interval) invalid format specifications.Bruce Momjian2005-08-18
|
* Fix to_char(interval) to return proper year and century values.Bruce Momjian2005-08-18
| | | | | | | | 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.
* Avoid an Assert failure if OuterUserId hasn't been set yet duringTom Lane2005-08-17
| | | | | AbortTransaction. This can happen if a backend's InitPostgres transaction fails (eg, because the given username is invalid). Per Alvaro.
* More formatting.c cleanups.Bruce Momjian2005-08-17
|
* Small cleanup.Bruce Momjian2005-08-17
|
* Adjust to_char/from_char code to use boolean "is_to_char" rather thanBruce Momjian2005-08-17
| | | | integer with flags.
* Rename pg_stat_file columns to be more consistent. Split apart changeBruce Momjian2005-08-15
| | | | and creation columns to behave for Unix or Win32.
* array_in() and array_recv() need to be more paranoid about validatingTom Lane2005-08-15
| | | | | | | | | 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.
* Clean up some stray remaining references to pg_shadow, pg_user, pg_group.Tom Lane2005-08-15

* Change standard_compliant_strings to standard_conforming_strings.Peter Eisentraut2005-08-14

* Tweak catalog cache management algorithms to reduce cost ofTom Lane2005-08-13
| | | | | | | | | | | | | | | | | SearchCatCacheList and ReleaseCatCacheList. Previously, we incremented and decremented the refcounts of list member tuples along with the list itself, but that's unnecessary, and very expensive when the list is big. It's cheaper to change only the list refcount. When we are considering deleting a cache entry, we have to check not only its own refcount but its parent list's ... but it's easy to arrange the code so that this check is not made in any commonly-used paths, so the cost is really nil. The bigger gain though is to refrain from DLMoveToFront'ing each individual member tuple each time the list is referenced. To keep some semblance of fair space management, lists are just marked as used or not since the last cache cleanout search, and we do a MoveToFront pass only when about to run a cleanout. In combination, these changes reduce the costs of SearchCatCacheList and ReleaseCatCacheList from about 4.5% of pgbench runtime to under 1%, according to my gprof results.
* Make pg_stat_file() use OUT parameters so that the user doesn't have toTom Lane2005-08-13
| | | | | | | 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.
