fad7e8edac Add text:
* Merge xmin/xmax/cmin/cmax back into three header fields

  Before subtransactions, there used to be only three fields needed to
  store these four values. This was possible because only the current
  transaction looks at the cmin/cmax values. If the current transaction
  created and expired the row the fields stored where xmin (same as
  xmax), cmin, cmax, and if the transaction was expiring a row from a
  another transaction, the fields stored were xmin (cmin was not
  needed), xmax, and cmax. Such a system worked because a transaction
  could only see committed rows from another transaction. However,
  subtransactions can see rows from outer transactions, and once the
  subtransaction completes, the outer transaction continues, requiring
  the storage of all four fields. With subtransactions, an outer
  transaction can create a row, a subtransaction expire it, and when the
  subtransaction completes, the outer transaction still has to have
  proper visibility of the row, for example, for cursors.

  One possible solution is to create a phantom cid which represents a
  cmin/cmax pair and is stored in local memory.

88d7b711a0 Remove completed items:
< * -Allow limits on per-db/role connections
43d41
< * -Prevent dropping user that still owns objects, or auto-drop the objects
49d46
< * -Add the client IP address and port to pg_stat_activity
< * -Add session start time and last statement time to pg_stat_activity
< * -Add a function that returns the start time of the postmaster
230d224
< 	o -Allow MIN()/MAX() on arrays
< 	o -Modify array literal representation to handle array index lower bound
< 	  of other than one
253d244
< * -Add function to return compressed length of TOAST data values
< * -Prevent to_char() on interval from returning meaningless values
<
<   For example, to_char('1 month', 'mon') is meaningless.  Basically,
<   most date-related parameters to to_char() are meaningless for
<   intervals because interval is not anchored to a date.
<
< * -Have views on temporary tables exist in the temporary namespace
< * -Allow temporary views on non-temporary tables
329d311
< * -Add BETWEEN SYMMETRIC/ASYMMETRIC
< * -Add E'' escape string marker so eventually ordinary strings can treat
<   backslashes literally, for portability
<
< * -Allow additional tables to be specified in DELETE for joins
<
<   UPDATE already allows this (UPDATE...FROM) but we need similar
<   functionality in DELETE.  It's been agreed that the keyword should
<   be USING, to avoid anything as confusing as DELETE FROM a FROM b.
<
341d313
< * -Allow REINDEX to rebuild all database indexes
< * -Add an option to automatically use savepoints for each statement in a
<   multi-statement transaction.
<
<   When enabled, this would allow errors in multi-statement transactions
<   to be automatically ignored.

642d592
< * -Allow triggers to be disabled
< * -Add two-phase commit
<
<
< * -Prevent inherited tables from expanding temporary subtables of other
<   sessions
< * -Use indexes for MIN() and MAX()
<
<   MIN/MAX queries can already be rewritten as SELECT col FROM tab ORDER
<   BY col {DESC} LIMIT 1. Completing this item involves doing this
<   transformation automatically.
<
< * -Use index to restrict rows returned by multi-key index when used with
<   non-consecutive keys to reduce heap accesses
<
<   For an index on col1,col2,col3, and a WHERE clause of col1 = 5 and
<   col3 = 9, spin though the index checking for col1 and col3 matches,
<   rather than just col1; also called skip-scanning.
<
< * -Fetch heap pages matching index entries in sequential order
<
<   Rather than randomly accessing heap pages based on index entries, mark
<   heap pages needing access in a bitmap and do the lookups in sequential
<   order. Another method would be to sort heap ctids matching the index
<   before accessing the heap rows.
<
< * -Allow non-bitmap indexes to be combined by creating bitmaps in memory
<
<   This feature allows separate indexes to be ANDed or ORed together.  This
<   is particularly useful for data warehousing applications that need to
<   query the database in an many permutations.  This feature scans an index
<   and creates an in-memory bitmap, and allows that bitmap to be combined
<   with other bitmap created in a similar way.  The bitmap can either index
<   all TIDs, or be lossy, meaning it records just page numbers and each
<   page tuple has to be checked for validity in a separate pass.
<
< * -Fix incorrect rtree results due to wrong assumptions about "over"
<   operator semantics
782d694
< 	o -Add concurrency to GIST
813d724
< * -Allow multiple blocks to be written to WAL with one write()
< * -Consider use of open/fcntl(O_DIRECT) to minimize OS caching,
<   for WAL writes
<
<   O_DIRECT doesn't have the same media write guarantees as fsync, so it
<   is in addition to the fsync method, not in place of it.
<
< * -Cache last known per-tuple offsets to speed long tuple access
< * -Allow the size of the buffer cache used by temporary objects to be
<   specified as a GUC variable
<
<   Larger local buffer cache sizes requires more efficient handling of
<   local cache lookups.
<
< * -Improve the background writer
<
<   Allow the background writer to more efficiently write dirty buffers
<   from the end of the LRU cache and use a clock sweep algorithm to
<   write other dirty buffers to reduced checkpoint I/O
<
897d788
< * -Add a warning when the free space map is too small
917d807
< 	o -Move into the backend code
< * -Make locking of shared data structures more fine-grained
<
<   This requires that more locks be acquired but this would reduce lock
<   contention, improving concurrency.
<
< * -Improve SMP performance on i386 machines
<
<   i386-based SMP machines can generate excessive context switching
<   caused by lock failure in high concurrency situations. This may be
<   caused by CPU cache line invalidation inefficiencies.
<
979d857
< 	o  -Add ability to turn off full page writes
< * -Eliminate WAL logging for CREATE TABLE AS when not doing WAL archiving
< * -Change WAL to use 32-bit CRC, for performance reasons
<
< * -Use CHECK constraints to influence optimizer decisions
<
<   CHECK constraints contain information about the distribution of values
<   within the table. This is also useful for implementing subtables where
<   a tables content is distributed across several subtables.
<
1045d913
< * -ANALYZE should record a pg_statistic entry for an all-NULL column
1099d966
< * -Remove kerberos4 from source tree
1103d969
< * -Make src/port/snprintf.c thread-safe
1118d983
< * -Add C code on Unix to copy directories for use in creating new databases

c6221db3c0 Updated text for bitmaps:
<   Bitmap indexes index single columns that can be combined with other bitmap
<   indexes to dynamically create a composite index to match a specific query.
<   Each index is a bitmap, and the bitmaps are bitwise AND'ed or OR'ed to be
<   combined.  They can index by tid or can be lossy requiring a scan of the
<   heap page to find matching rows, or perhaps use a mixed solution where
<   tids are recorded for pages with only a few matches and per-page bitmaps
<   are used for more dense pages.  Another idea is to use a 32-bit bitmap
<   for every page and set a bit based on the item number mod(32).

>   This feature allows separate indexes to be ANDed or ORed together.  This
>   is particularly useful for data warehousing applications that need to
>   query the database in an many permutations.  This feature scans an index
>   and creates an in-memory bitmap, and allows that bitmap to be combined
>   with other bitmap created in a similar way.  The bitmap can either index
>   all TIDs, or be lossy, meaning it records just page numbers and each
>   page tuple has to be checked for validity in a separate pass.
