(they are not part of a chain). When failing to find a parent tuple in
an update chain, emit a warning and abandon repair_frag, but do not give
an error as before. This should eliminate the infamous 'No one parent tuple
was found' failure, which we now realize is not a can't-happen condition
but a perfectly valid database state. Per recent pghackers discussion.
heap_mark4update; this avoids situations where a deleted tuple might
look like it is chained to something else. Also, cause all the WAL
redo routines to set t_ctid to equal t_self, rather than leaving it
undefined as before. Make heap_xlog_clean set the page's LSN and SUI
correctly. All per past discussions in pghackers, ranging back to
last December.
to make a reasonable attempt at accounting for palloc overhead, not just
the requested size of each memory chunk. Since in many scenarios this
will make for a significant reduction in the amount of space acquired,
partially compensate by doubling the default value of SORT_MEM to 1Mb.
Per discussion in pgsql-general around 9-Jun-2002..
it takes could be held for quite awhile after the analyze step completes.
Rethink locking of pg_statistic in light of this fact. The original
scheme took an exclusive lock on pg_statistic, which was okay when the
lock could be expected to be released shortly, but that doesn't hold
anymore. Back off to a normal writer's lock (RowExclusiveLock). This
allows concurrent ANALYZE of nonoverlapping sets of tables, at the price
that concurrent ANALYZEs of the same table may fail with 'tuple
concurrently updated'.

I update two tuples, so I manually CatalogOpenIndexes() and
CatalogIndexInsert() two times, as per comments in
CatalogUpdateIndexes().
I also removed a couple of useless CommandCounterIncrement(), some
useless definitions in src/include/commands/cluster.h and useless
includes in src/backend/commands/cluster.c. This version passes the
regression test I had made for previous versions.

Reported by Neil Conway -- I never implemented readfuncs.c support for
ColumnDef or TypeName, which is needed so that views can be created on
functions returning type RECORD. Here's a patch.

relfilenode.
I sent the CLUSTER patch a few days ago and I think it was missed. I
append it again, this time including the regression test files. For the
committer, please note that you have to cvs add the files as they don't
exist. Maybe add to the parallel and serial schedules also, but I don't
know such stuff.

1. Reworked patch from Andrey Oktyabrski (ano@spider.ru) with
functions: icount, sort, sort_asc, uniq, idx, subarray
operations: #, +, -, |, &
FUNCTIONS:
int icount(int[]) - the number of elements in intarray
int[] sort(int[], 'asc' | 'desc') - sort intarray
int[] sort(int[]) - sort in ascending order
int[] sort_asc(int[]),sort_desc(int[]) - shortcuts for sort
int[] uniq(int[]) - returns unique elements
int idx(int[], int item) - returns index of first intarray matching element
to item, or '0' if matching failed.
int[] subarray(int[],int START [, int LEN]) - returns part of intarray
starting from element number START (from 1)
and length LEN.
OPERATIONS:
int[] && int[] - overlap - returns TRUE if arrays has at least one common elements.
int[] @ int[] - contains - returns TRUE if left array contains right array
int[] ~ int[] - contained - returns TRUE if left array is contained in right array
# int[] - return the number of elements in array
int[] + int - push element to array ( add to end of array)
int[] + int[] - merge of arrays (right array added to the end of left one)
int[] - int - remove entries matched by right argument from array
int[] - int[] - remove left array from right
int[] | int - returns intarray - union of arguments
int[] | int[] - returns intarray as a union of two arrays
int[] & int[] - returns intersection of arrays

error handling, and simplifies the code that remains. Apparently,
the code that left Berkeley had a whole "error handling subsystem",
which exceptions and whatnot. Since we don't use that anymore,
there's no reason to keep it around.
The regression tests pass with the patch applied. Unless anyone
sees a problem, please apply.
Neil Conway
has_language_privilege, has_schema_privilege to let SQL queries test
all the new privilege types in 7.3. Also, add functions pg_table_is_visible,
pg_type_is_visible, pg_function_is_visible, pg_operator_is_visible,
pg_opclass_is_visible to test whether objects contained in schemas are
visible in the current search path. Do some minor cleanup to centralize
accesses to pg_database, as well.
