* The random selection in function linear() could deliver a value equal to maxTom Lane2005-06-14
| | | | | | | if geqo_rand() returns exactly 1.0, resulting in failure due to indexing off the end of the pool array. Also, since this is using inexact float math, it seems wise to guard against roundoff error producing values slightly outside the expected range. Per report from bug@zedware.org.
* Fix bug in MIC -> EUC_JP conversion. Per Atsushi Ogawa.Tatsuo Ishii2005-06-11

* Code for SET/SHOW TIME ZONE with a fixed-interval timezone was notTom Lane2005-06-05
| | | | prepared for HAVE_INT64_TIMESTAMP. Per report from Guillaume Beaudoin.
* Push enable/disable of notify and catchup interrupts all the way downTom Lane2005-06-02
| | | | | | | to just around the bare recv() call that gets a command from the client. The former placement in PostgresMain was unsafe because the intermediate processing layers (especially SSL) use facilities such as malloc that are not necessarily re-entrant. Per report from counterstorm.com.
* Add test to WAL replay to verify that xl_prev points back to the previousTom Lane2005-05-31
| | | | | WAL record; this is necessary to be sure we recognize stale WAL records when a WAL page was only partially written during a system crash.
* expandRTE and get_rte_attribute_type mistakenly always imputed typmod -1Tom Lane2005-05-29
| | | | | | to columns of an RTE that was a function returning RECORD with a column definition list. Apparently no one has tried to use non-default typmod with a function returning RECORD before.
* Adjust datetime parsing to be more robust. We now pass the length of theNeil Conway2005-05-26
| | | | | | | | | | | | | | | working buffer into ParseDateTime() and reject too-long input there, rather than checking the length of the input string before calling ParseDateTime(). The old method was bogus because ParseDateTime() can use a variable amount of working space, depending on the content of the input string (e.g. how many fields need to be NUL terminated). This fixes a minor stack overrun -- I don't _think_ it's exploitable, although I won't claim to be an expert. Along the way, fix a bug reported by Mark Dilger: the working buffer allocated by interval_in() was too short, which resulted in rejecting some perfectly valid interval input values. I added a regression test for this fix.

* Inserting 5 characters into char(10) does not produce 5 padding spacesTatsuo Ishii2005-05-24
| | | | | | if they are two-byte multibyte characters. Same thing can be happen if octet_length(multibyte_chars) == n where n is char(n). Long standing bug since 7.3 days. Per report and fix from Yoshiyuki Asaba.
* Previous fix for "x FULL JOIN y ON true" failed to handle the caseTom Lane2005-05-24
| | | | | | | where there was also a WHERE-clause restriction that applied to the join. The check on restrictlist == NIL is really unnecessary anyway, because select_mergejoin_clauses already checked for and complained about any unmergejoinable join clauses. So just take it out.
* Repair very-low-probability race condition between relation extensionTom Lane2005-05-07
| | | | | | | | and VACUUM: in the interval between adding a new page to the relation and formatting it, it was possible for VACUUM to come along and decide it should format the page too. Though not harmful in itself, this would cause data loss if a third transaction were able to insert tuples into the vacuumed page before the original extender got control back.
* Adjust time qual checking code so that we always check TransactionIdIsInProgressTom Lane2005-05-07
| | | | | | | before we check commit/abort status. Formerly this was done in some paths but not all, with the result that a transaction might be considered committed for some purposes before it became committed for others. Per example found by Jan Wieck.
* Make standalone backends ignore pg_database.datallowconn, so that thereTom Lane2005-05-05
| | | | is a way to recover from disabling connections to all databases at once.
* Alter the signature for encoding conversion functions to declare theTom Lane2005-05-03
| | | | | | output area as INTERNAL not CSTRING. This is to prevent people from calling the functions by hand. This is a permanent solution for the back branches but I hope it is just a stopgap for HEAD.
* Change tsearch2 to not use the unsafe practice of creating functionsTom Lane2005-05-03
| | | | | | | | that return INTERNAL without also having INTERNAL arguments. Since the functions in question aren't meant to be called by hand anyway, I just redeclared them to take 'internal' instead of 'text'. Also add code to ProcedureCreate() to enforce the restriction, as I should have done to start with :-(
* GCC 4.0 includes a new warning option, -Wformat-literal, that emitsNeil Conway2005-04-30
| | | | | | | | | | | | | | | a warning when a variable is used as a format string for printf() and similar functions (if the variable is derived from untrusted data, it could include unexpected formatting sequences). This emits too many warnings to be enabled by default, but it does flag a few dubious constructs in the Postgres tree. This patch fixes up the obvious variants: functions that are passed a variable format string but no additional arguments. Most of these are harmless (e.g. the ruleutils stuff), but there is at least one actual bug here: if you create a trigger named "%sfoo", pg_dump will read uninitialized memory and fail to dump the trigger correctly.
* Repair two TIME WITH TIME ZONE bugs found by Dennis Vshivkov. ComparisonTom Lane2005-04-23
| | | | | | | of timetz values misbehaved in --enable-integer-datetime cases, and EXTRACT(EPOCH) subtracted the zone instead of adding it in all cases. Backpatch to all supported releases (except --enable-integer-datetime code does not exist in 7.2).
* Don't try to run clauseless index scans on index types that don't supportTom Lane2005-04-20
| | | | it. Per report from Marinos Yannikos.
* Fix mis-display of negative fractional seconds in interval values forTom Lane2005-04-20
| | | | --enable-integer-datetimes case. Per report from Oliver Siegmar.
* Don't try to constant-fold functions returning RECORD, since the optimizerTom Lane2005-04-14
| | | | | isn't presently set up to pass them an expected tuple descriptor. Bug has been there since 7.3 but was just recently reported by Thomas Hallgren.
* Make constant-folding produce sane output for COALESCE(NULL,NULL),Tom Lane2005-04-10
| | | | | that is a plain NULL and not a COALESCE with no inputs. Fixes crash reported by Michael Williamson.
* In cost_mergejoin, the early-exit effect should not apply to theTom Lane2005-04-04
| | | | outer side of an outer join. Per andrew@supernews.
* Flush any remaining statistics counts out to the collector at processTom Lane2005-03-31
| | | | | | | | exit. Without this, operations triggered during backend exit (such as temp table deletions) won't be counted ... which given heavy usage of temp tables can lead to pg_autovacuum falling way behind on the need to vacuum pg_class and pg_attribute. Per reports from Steve Crawford and others.
* Prevent to_char(interval) from dumping core on month-related formatsTom Lane2005-03-26
| | | | when a zero-month interval is given. Per discussion with Karel.
* array_map can't use the fn_extra field of the provided fcinfo struct asTom Lane2005-03-24
| | | | | its private storage, because that belongs to the function that it is supposed to call. Per report from Ezequiel Tolnay.
* Fix ALTER DATABASE RENAME to allow the operation if user is a superuserTom Lane2005-03-12
| | | | | who for some reason isn't marked usecreatedb. Per report from Alexander Pravking. Also fix sloppy coding in have_createdb_privilege().
* Release proclock immediately in RemoveFromWaitQueue() if it representsTom Lane2005-03-01
| | | | | | no held locks. This maintains the invariant that proclocks are present only for procs that are holding or awaiting a lock; when this is not true, LockRelease will fail. Per report from Stephen Clouse.
* Ensure that the resolved datatype of any unknown Param is propagatedTom Lane2005-02-19
| | | | | into the sub-SELECT targetlist when it appears in the context INSERT INTO foo SELECT $1 ... Per report from Abhijit Menon-Sen.

* Back-patch fix for a typo that unintentionally disabled backward scansTom Lane2005-02-10
| | | | for all SPI-created cursors.
* Repair CLUSTER failure after ALTER TABLE SET WITHOUT OIDS. Turns outTom Lane2005-02-06
| | | | | | | there are corner cases involving dropping toasted columns in which the previous coding would fail, too: the new version of the table might not have any TOAST table, but we'd still propagate possibly-wide values of dropped columns forward.
* Back-port heap_deformtuple() into 7.4 branch; needed for planned fix forTom Lane2005-02-06

* The result of a FULL or RIGHT join can't be assumed to be sorted by theTom Lane2005-01-23

* interval_out failed to mention 'ago' for negative intervals in SQL andTom Lane2005-01-11
| | | | GERMAN datestyles. Ancient bug reported by Terry Lee Tucker.
* Avoid memory leakage during VACUUM FULL when an index expression orTom Lane2004-12-23

* array_map failed to insert correct result type in an empty array.Tom Lane2004-12-17

* Use StrNCpy not strncpy to fill hash key, to ensure the resulting keyTom Lane2004-12-03
| | | | | | is null-terminated. I think this is not a real bug because the parser would always have truncated the identifier to NAMEDATALEN-1 already, but let's be safe. Per report from Klocwork.

* Teach regex_fixed_prefix() the correct handling of advanced regexTom Lane2004-12-02
| | | | | | escapes --- they aren't simply quoted characters. Problem noted by Antti Salmela. Also fix problem with incorrect handling of multibyte characters when followed by a quantifier.
