* Adjust citext to make use of the new ability to declare its type category:Tom Lane2008-07-30
| | | | | | | | by putting it into the standard string category, we cause casts from citext to text to be recognized as "preferred" casts. This eliminates the need for creation of alias functions and operators that only serve to prevent ambiguous-function errors; get rid of the ones that were in the original commit.
* Replace the hard-wired type knowledge in TypeCategory() and IsPreferredType()Tom Lane2008-07-30
| | | | | | | | | | | | | | | | | | | | | with system catalog lookups, as was foreseen to be necessary almost since their creation. Instead put the information into two new pg_type columns, typcategory and typispreferred. Add support for setting these when creating a user-defined base type. The category column is just a "char" (i.e. a poor man's enum), allowing a crude form of user extensibility of the category list: just use an otherwise-unused character. This seems sufficient for foreseen uses, but we could upgrade to having an actual category catalog someday, if there proves to be a huge demand for custom type categories. In this patch I have attempted to hew exactly to the behavior of the previous hardwired logic, except for introducing new type categories for arrays, composites, and enums. In particular the default preferred state for user-defined types remains TRUE. That seems worth revisiting, but it should be done as a separate patch from introducing the infrastructure. Likewise, any adjustment of the standard set of categories should be done separately.

* As noted by Andrew Gierth, there's really no need any more to force a junkTom Lane2008-07-26
| | | | | | | | | | | | | | | | filter to be used when INSERT or SELECT INTO has a plan that returns raw disk tuples. The virtual-tuple-slot optimizations that were put in place awhile ago mean that ExecInsert has to do ExecMaterializeSlot, and that already copies the tuple if it's raw (and does so more efficiently than a junk filter, too). So get rid of that logic. This in turn means that we can throw away ExecMayReturnRawTuples, which wasn't used for any other purpose, and was always a kluge anyway. In passing, move a couple of SELECT-INTO-specific fields out of EState and into the private state of the SELECT INTO DestReceiver, as was foreseen in an old comment there. Also make intorel_receive use ExecMaterializeSlot not ExecCopySlotTuple, for consistency with ExecInsert and to possibly save a tuple copy step in some cases.

* Use guc.c's parse_int() instead of pg_atoi() to parse fillfactor inTom Lane2008-07-23
| | | | | | | | | | default_reloptions(). The previous coding was really a bug because pg_atoi() will always throw elog on bad input data, whereas default_reloptions is not supposed to complain about bad input unless its validate parameter is true. Right now you could only expose the problem by hand-modifying pg_class.reloptions into an invalid state, so it doesn't seem worth back-patching; but we should get it right in HEAD because there might be other situations in future. Noted while studying GIN fast-update patch.

* Avoid substituting NAMEDATALEN, FLOAT4PASSBYVAL, and FLOAT8PASSBYVAL intoTom Lane2008-07-19
| | | | | | | | | the postgres.bki file during build, because we want that file to be entirely platform- and configuration-independent; else it can't safely be put into /usr/share on multiarch machines. We can do the substitution during initdb, instead. FLOAT4PASSBYVAL and FLOAT8PASSBYVAL are new breakage as of 8.4, while the NAMEDATALEN hazard has been there all along but I guess no one tripped over it. Noticed while trying to build "universal" OS X binaries.
* Adjust things so that the query_string of a cached plan and the sourceText ofTom Lane2008-07-18
| | | | | | | | | | | | | | | | | | | | | | | | a portal are never NULL, but reliably provide the source text of the query. It turns out that there was only one place that was really taking a short-cut, which was the 'EXECUTE' utility statement. That doesn't seem like a sufficiently critical performance hotspot to justify not offering a guarantee of validity of the portal source text. Fix it to copy the source text over from the cached plan. Add Asserts in the places that set up cached plans and portals to reject null source strings, and simplify a bunch of places that formerly needed to guard against nulls. There may be a few places that cons up statements for execution without having any source text at all; I found one such in ConvertTriggerToFK(). It seems sufficient to inject a phony source string in such a case, for instance ProcessUtility((Node *) atstmt, "(generated ALTER TABLE ADD FOREIGN KEY command)", NULL, false, None_Receiver, NULL); We should take a second look at the usage of debug_query_string, particularly the recently added current_query() SQL function.

* Fix a race condition that I introduced into sinvaladt.c during the recentTom Lane2008-07-18
| | | | | | | | | rewrite. When called from SIInsertDataEntries, SICleanupQueue releases the write lock if it has to issue a kill() to signal some laggard backend. That still seems like a good idea --- but it's possible that by the time we get the lock back, there are no longer enough free message slots to satisfy SIInsertDataEntries' requirement. Must recheck, and repeat the whole SICleanupQueue process if not. Noted while reading code.

| | | | | | | | | | need to deconstruct proargmodes for each pg_proc entry inspected by FuncnameGetCandidates(). Fixes function lookup performance regression caused by yesterday's variadic-functions patch. In passing, make pg_proc.probin be NULL, rather than a dummy value '-', in cases where it is not actually used for the particular type of function. This should buy back some of the space cost of the extra column.

* Support "variadic" functions, which can accept a variable number of argumentsTom Lane2008-07-16
| | | | | | | | | | | | | | so long as all the trailing arguments are of the same (non-array) type. The function receives them as a single array argument (which is why they have to all be the same type). It might be useful to extend this facility to aggregates, but this patch doesn't do that. This patch imposes a noticeable slowdown on function lookup --- a follow-on patch will fix that by adding a redundant column to pg_proc. Pavel Stehule
