* 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 up LIMIT/OFFSET planning so that we cope with non-constant LIMITTom Lane2005-08-18
| | | | | | | | | | or OFFSET clauses by using estimate_expression_value(). The main advantage of this is that if the expression is a Param and we have a value for the Param, we'll use that value rather than defaulting. Also, fix some thinkos in the logic for combining LIMIT/OFFSET with an externally supplied tuple fraction (this covers cases like EXISTS(...LIMIT...)). And make sure the results of all this are shown by EXPLAIN. Per a gripe from Merlin Moncure.

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.
* Allow the pgstat views to show toast tables as well as regular tablesTom Lane2005-08-15
| | | | | | | | (the stats system has always collected this info, but the views were filtering it out). Modify autovacuum so that over-threshold activity in a toast table can trigger a VACUUM of the parent table, even if the parent didn't appear to need vacuuming itself. Per discussion a month or so back about "short, wide tables".

* 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.

Here we go, that wasn't too hard :-) Apart from adding the error handling, it does one more thing: it changes the errormode when loading the DLLs. Previously if a DLL was broken, or referenced other DLLs that couldn't be found, a popup dialog box would appear on the screen. Which had to be clicked before the backend could continue. This patch also disables the popup error message for DLL loads. I think this is something we should consider doing for the entire backend - disable those popups, and say we deal with it ourselves. What do you other win32 hackers thinnk about this? In the meantime, this patch fixes the error msgs. Please apply for 8.1 and please consider a backpatch to 8.0. Magnus Hagander

Yeah, its not that exciting but that error message would throw your average user. I've attached a patch which calls CommandCounterIncrement() in each of the grant loops. Gavin Sherry
