* Get rid of a bunch of dubious error handling code in pgbench by just erroringTom Lane2010-08-12
| | | | | | out immediately on any out-of-memory condition. It's rather pointless to imagine that pgbench will be able to continue usefully after a malloc failure, and in any case there were a number of unchecked mallocs.
* Add the ability to compute per-statement latencies (ie, average executionTom Lane2010-08-12

* Extend psql's \e and \ef commands so that a line number can be specified,Tom Lane2010-08-12
| | | | | | | | | | | | | | | | | | and the editor's cursor will be initially placed on that line. In \e the lines are counted with respect to the query buffer, while in \ef they are counted with line 1 = first line of function body. These choices are useful for positioning the cursor on the line of a previously-reported error. To avoid assumptions about what switch the user's editor takes for this purpose, invent a new psql variable EDITOR_LINENUMBER_SWITCH with (at present) no default value. One incompatibility from previous behavior is that "\e 1234" will now take "1234" as a line number not a file name. There are at least two ways to select a numerically-named file if you really want to. Pavel Stehule, reviewed by Jan Urbanski, with further editing by Robert Haas and Tom Lane

* Fix incorrect errno definitions in ECPG manual.Robert Haas2010-08-11
| | | | | | | ecpgerrno.h hasn't materially changed since PostgreSQL 7.4, so this has been wrong for a very long time. Back-patch all the way. Satoshi Nagayasu
* Remove the arbitrary (and undocumented) limit on the number of parameter=valueTom Lane2010-08-10
| | | | | | | | | pairs that can be handled by xslt_process(). There is much else to do here, but this patch seems useful in its own right for as long as this code survives. Pavel Stehule, reviewed by Mike Fowler
* Add three-parameter forms of array_to_string and string_to_array, to allowTom Lane2010-08-10
| | | | | | | | | | | | | | | | better handling of NULL elements within the arrays. The third parameter is a string that should be used to represent a NULL element, or should be translated into a NULL element, respectively. If the third parameter is NULL it behaves the same as the two-parameter form. There are two incompatible changes in the behavior of the two-parameter form of string_to_array. First, it will return an empty (zero-element) array rather than NULL when the input string is of zero length. Second, if the field separator is NULL, the function splits the string into individual characters, rather than returning NULL as before. These two changes make this form fully compatible with the behavior of the new three-parameter form. Pavel Stehule, reviewed by Brendan Jurd

* Use double quotes rather than double quotes for libpq target anchors.Robert Haas2010-08-10
| | | | | Per observation from Tom Lane that the previous patch to these files was not consistent with what is done elsewhere in the docs.
* Fix incorrect logic in plpgsql for cleanup after evaluation of non-simpleTom Lane2010-08-09
| | | | | | | | | | | | | expressions. We need to deal with this when handling subscripts in an array assignment, and also when catching an exception. In an Assert-enabled build these omissions led to Assert failures, but I think in a normal build the only consequence would be short-term memory leakage; which may explain why this wasn't reported from the field long ago. Back-patch to all supported versions. 7.4 doesn't have exceptions, but otherwise these bugs go all the way back. Heikki Linnakangas and Tom Lane

* Modify the handling of RAISE without parameters so that the error it throwsTom Lane2010-08-09
| | | | | | | | | | | | | can be caught in the same places that could catch an ordinary RAISE ERROR in the same location. The previous coding insisted on throwing the error from the block containing the active exception handler; which is arguably more surprising, and definitely unlike Oracle's behavior. Not back-patching, since this is a pretty obscure corner case. The risk of breaking somebody's code in a minor version update seems to outweigh any possible benefit.

* Add stats functions and views to provide access to a transaction's ownTom Lane2010-08-08
| | | | | | | | statistics counts. These numbers are being accumulated but haven't yet been transmitted to the collector (and won't be, until the transaction ends). For some purposes, though, it's handy to be able to look at them. Joel Jacobson, reviewed by Itagaki Takahiro

* Recognize functional dependency on primary keys. This allows a table'sTom Lane2010-08-07
| | | | | | | | | | | | | other columns to be referenced without listing them in GROUP BY, so long as the primary key column(s) are listed in GROUP BY. Eventually we should also allow functional dependency on a UNIQUE constraint when the columns are marked NOT NULL, but that has to wait until NOT NULL constraints are represented in pg_constraint, because we need to have pg_constraint OIDs for all the conditions needed to ensure functional dependency.

* Add a very specific hint for the case that we're unable to locate a functionTom Lane2010-08-05
| | | | | | | matching a call like f(x, ORDER BY y,z). It could be that what the user really wants is f(x,z ORDER BY y). We now have pretty conclusive evidence that many people won't understand this problem without concrete guidance, so give it to them. Per further discussion of the string_agg() problem.

* Remove the single-argument form of string_agg(). It added nothing much inTom Lane2010-08-05
| | | | | | | | functionality, while creating an ambiguity in usage with ORDER BY that at least two people have already gotten seriously confused by. Also, add an opr_sanity test to check that we don't in future violate the newly minted policy of not having built-in aggregates with the same name and different numbers of parameters. Per discussion of a complaint from Thom Brown.
* Standardize get_whatever_oid functions for other object types.Robert Haas2010-08-05
| | | | | | | | | | | | | | | - Rename TSParserGetPrsid to get_ts_parser_oid. - Rename TSDictionaryGetDictid to get_ts_dict_oid. - Rename TSTemplateGetTmplid to get_ts_template_oid. - Rename TSConfigGetCfgid to get_ts_config_oid. - Rename FindConversionByName to get_conversion_oid. - Rename GetConstraintName to get_constraint_oid. - Add new functions get_opclass_oid, get_opfamily_oid, get_rewrite_oid, get_rewrite_oid_without_relid, get_trigger_oid, and get_cast_oid. The name of each function matches the corresponding catalog. Thanks to KaiGai Kohei for the review.

* Fix declared argument name for numeric_maximum_size.Robert Haas2010-08-04
| | | | | The previous commit changed the function to say 'typmod' rather than 'typemod', but I forgot to update the header file.
* Fix numeric_maximum_size() calculation.Robert Haas2010-08-04
| | | | | | | | The old computation can sometimes underestimate the necessary space by 2 bytes; however we're not back-patching this, because this result isn't used for anything critical. Per discussion with Tom Lane, make the typmod test in this function match the ones in numeric() and apply_typmod() exactly.

* Fix inheritance count tracking in ALTER TABLE .. ADD CONSTRAINT.Robert Haas2010-08-03
| | | | | | | | | | | | | | Without this patch, constraints inherited by children of a parent table which itself has multiple inheritance parents can end up with the wrong coninhcount. After dropping the constraint, the children end up with a leftover copy of the constraint that is not dumped and cannot be dropped. There is a similar problem with ALTER TABLE .. ADD COLUMN, but that looks significantly more difficult to resolve, so I'm committing this fix separately. Back-patch to 8.4, which is the first release that has coninhcount. Report by Hank Enting.

* Be a little more careful with the shift computations in QT2QTN andTom Lane2010-08-03
| | | | | | | | makeTSQuerySign. The first of these is a live bug, on some platforms, as per bug #5590 from John Regehr. However the consequences seem limited because of the relatively narrow scope of use of QTNode.sign. The shift in makeTSQuerySign is actually safe because TSQS_SIGLEN is unsigned, but it seems like a good idea to insert an explicit cast rather than depend on that.
* Fix core dump in QTNodeCompare when tsquery_cmp() is applied to two emptyTom Lane2010-08-03
| | | | | | | | | | | | | | tsqueries. CompareTSQ has to have a guard for the case rather than blindly applying QTNodeCompare to random data past the end of the datums. Also, change QTNodeCompare to be a little less trusting: use an actual test rather than just Assert'ing that the input is sane. Problem encountered while investigating another issue (I saw a core dump in autoanalyze on a table containing multiple empty tsquery values). Back-patch to all branches with tsquery support. In HEAD, also fix some bizarre (though not outright wrong) coding in tsq_mcontains().
