<
< 	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
<    starvation
<
<    The problem is that autovacuum cannot vacuum them to set frozen xids;

< * Add connection pooling
<
<   It is unclear if this should be done inside the backend code or done
<   by something external like pgpool. The passing of file descriptors to
<   existing backends is one of the difficulties with a backend approach.
<
< * Consider reducing memory used for shared buffer reference count

< * 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
< * Split out libpq pgpass and environment documentation sections to make

<   multiple I/O channels simultaneously.  One idea is to create a
<   background reader that can pre-fetch sequential and index scan
<   pages needed by other backends.  This could be expanded to allow

<
<   Posix_fadvise() can control both sequential/random file caching and
<   free-behind behavior, but it is unclear how the setting affects other

< 	o Allow UPDATE/DELETE WHERE CURRENT OF cursor
<
< 	  This requires using the row ctid to map cursor rows back to the
< 	  original heap row. This become more complicated if WITH HOLD cursors
< 	  are to be supported because WITH HOLD cursors have a copy of the row
< 	  and no FOR UPDATE lock.

<   One possible implementation is to start sequential scans from the lowest

ededa6dfc8 TODO item not needed anymore now that the buffer cache is
scan-resistant:

<
< * Allow free-behind capability for large sequential scans, perhaps using
<   posix_fadvise()
<
<   Posix_fadvise() can control both sequential/random file caching and
<   free-behind behavior, but it is unclear how the setting affects other
<   backends that also have the file open, and the feature is not supported
<   on all operating systems.
