< 	o To better utilize resources, restore data, primary keys, and
<  	  indexes for a single table before restoring the next table
<
< 	  Hopefully this will allow the CPU-I/O load to be more uniform
< 	  for simultaneous restores.  The idea is to start data restores
< 	  for several objects, and once the first object is done, to move
< 	  on to its primary keys and indexes.  Over time, simultaneous
< 	  data loads and index builds will be running.

< * Improve replication solutions
<
< 	o Load balancing
<
< 	  You can use any of the master/slave replication servers to use a
< 	  standby server for data warehousing. To allow read/write queries to
< 	  multiple servers, you need multi-master replication like pgcluster.
<
< 	o Allow replication over unreliable or non-persistent links
<
<
< 	o Mark change-on-restart-only values in postgresql.conf
< 	  All objects in the default database tablespace must have default
< 	  tablespace specifications. This is because new databases are
< 	  created by copying directories. If you mix default tablespace
< 	  tables and tablespace-specified tables in the same directory,
< 	  creating a new database from such a mixed directory would create a
< 	  new database with tables that had incorrect explicit tablespaces.
< 	  To fix this would require modifying pg_class in the newly copied
< 	  database, which we don't currently do.

< * Reduce lock time during VACUUM FULL by moving tuples with read lock,
<   then write lock and truncate table
<
<   Moved tuples are invisible to other backends so they don't require a
<   write lock. However, the read lock promotion to write lock could lead
<   to deadlock situations.
<
< * Prevent long-lived temporary tables from causing frozen-xid advancement

< * Add connection pooling
<
<   It is unclear if this should be done inside the backend code or done

< * Allow ecpg to work with MSVC and BCC
< * Add xpath_array() to /contrib/xml2 to return results as an array
< * Allow building in directories containing spaces
<
<   This is probably not possible because 'gmake' and other compiler tools
<   do not fully support quoting of paths with spaces.
<
< * Fix sgmltools so PDFs can be generated with bookmarks

< * 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 rows from another completed 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's cmin, 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.  Another idea is to
<   store both cmin and cmax only in local memory.

aa3f396aca Remove completed TODO items:
< * -Make postmater and postgres options distinct so the postmaster -o
<   option is no longer needed
< * -Allow pooled connections to list all prepared statements
<
<   This would allow an application inheriting a pooled connection to know
<   the statements prepared in the current session.
<
< * -Re-enable the GUC full_page_writes in 8.2 when reliability issues have
<   been addressed
< 	o -Add "include file" functionality in postgresql.conf
< 	o -Allow per-database permissions to be set via GRANT
<
< 	  Allow database connection checks based on GRANT rules in
< 	  addition to the existing access checks in pg_hba.conf.
<
< 	o -Issue a warning if a change-on-restart-only postgresql.conf value
> 	o Issue a warning if a change-on-restart-only postgresql.conf value
< 	  o -Automatically force archiving of partially-filled WAL files when
< 	    pg_stop_backup() is called or the server is stopped
< 	  o -Add reporting of the current WAL file and offset, perhaps as
< 	    part of partial log file archiving
< * -Allow server logs to be remotely read and removed using SQL commands
< * -Allow protocol-level BIND parameter values to be logged
< * -Zero umasked bits in conversion from INET cast to CIDR
< * -Prevent INET cast to CIDR from dropping netmask, SELECT '1.1.1.1'::inet::cidr
< * -Allow INET + INT8 to increment the host part of the address or
<   throw an error on overflow
< * -Add 'tid != tid ' operator for use in corruption recovery
< 	o -Allow customization of the known set of TZ names (generalize the
< 	  present australian_timezones hack)
< 	o -Allow timezone names in SQL strings, '2006-05-24 21:11
< 	   Americas/New_York'::timestamptz
< 		o -Add support for day-time syntax, INTERVAL '1 2:03:04' DAY TO
< 		  SECOND
< 	o -Allow NULLs in arrays
< * -Add transaction_timestamp(), statement_timestamp(), clock_timestamp()
<   functionality
<
<   Current CURRENT_TIMESTAMP returns the start time of the current
<   transaction, and gettimeofday() returns the wallclock time. This will
<   make time reporting more consistent and will allow reporting of
<   the statement start time.
<
< * -Allow to_char() to print localized month names
< * -Add sleep() function, remove from regress.c
< * -Allow user-defined functions retuning a domain value to enforce domain
<   constraints
< * -Allow TRUNCATE ... CASCADE/RESTRICT
<
<   This is like DELETE CASCADE, but truncates.
<
< * -Add COMMENT ON for all cluster global objects (roles, databases
<   and tablespaces)
< * -Make row-wise comparisons work per SQL spec
<
<   Right now, '(a, b) < (1, 2)' is processed as 'a < 1 and b < 2', but
<   the SQL standard requires it to be processed as a column-by-column
<   comparison, so the proper comparison is '(a < 1) OR (a = 1 AND b < 2)'.
<
< * -Enable escape_string_warning and standard_conforming_strings
> * Enable standard_conforming_strings
< 	o -Add ON COMMIT capability to CREATE TABLE AS ... SELECT
< 	o -Allow an alias to be provided for the target table in
< 	  UPDATE/DELETE (Neil)
< 	o -Allow UPDATE tab SET ROW (col, ...) = (val, ...) for updating
< 	  multiple columns
< 	o -Add ALTER TABLE tab INHERIT / NO INHERIT  parent
< 	o -Have COPY return the number of rows loaded/unloaded?
< 	o -Allow COPY (SELECT ...) TO 'filename'
<
< 	o -Allow pooled connections to list all open WITH HOLD cursors
<
< 	  Because WITH HOLD cursors exist outside transactions, this allows
< 	  them to be listed so they can be closed.
<
< 	o -Allow INSERT INTO tab (col1, ..) VALUES (val1, ..), (val2, ..)
< 	o -Allow INSERT/UPDATE ... RETURNING new.col or old.col
< 		o -Allow PL/python to return composite types and result sets
<
< * -Have initdb set the input DateStyle (MDY or DMY) based on locale
< 	o -Improve psql's handling of multi-line statements
<
< 	  Currently, while \e saves a single statement as one entry, interactive
< 	  statements are saved one line at a time.  Ideally all statements
< 	  would be saved like \e does.
<
< 	o -Allow multi-line column values to align in the proper columns
<
< 	  If the second output column value is 'a\nb', the 'b' should appear
< 	  in the second display column, rather than the first column as it
< 	  does now.
<
< 	o -Display IN, INOUT, and OUT parameters in \df
< 	o -Allow pg_dump to use multiple -t and -n switches, exclusion
< 	   ability, and regular expression object matching
< 	o -Update pg_dump and psql to use the new COPY libpq API (Christopher)
< 	o -Add a function to support Parse/DescribeStatement capability
< * -Add fillfactor to control reserved free space during index creation
< * -Add system view to show free space map contents
< * -Allow installing to directories containing spaces
<
<   This is possible if proper quoting is added to the makefiles for the
<   install targets.  Because PostgreSQL supports relocatable installs, it
<   is already possible to install into a directory that doesn't contain
<   spaces and then copy the install to a directory with spaces.
<
< * -%Clean up compiler warnings (especially with gcc version 4)
< * -Remove BeOS and QNX-specific code
< 	o -Port contrib/xml2

f204274191 Update TODO for short header versions:
< 	o Reorder physical storage order to reduce padding?
<
< 	  This involves having the user-specified order of columns
< 	  be different from the physical order.  SELECT * would
< 	  need to reorder the physical values to match the
< 	  user-specified ordering.
<
< 	o Store disk pages with no alignment/padding?
<
< 	  This necessitates adding CPU-required padding when moving
< 	  rows from disk to memory.
<
< 	  One idea is to store the header in network byte order (high bits
< 	  first), and read the high bits to determine the header length.
< 	  http://archives.postgresql.org/pgsql-hackers/2006-09/msg00848.php
