Release 7.1
|
||||||
|
|
||||||
|
This release focuses on removing limitations that have existed in the
|
||||||
|
PostgreSQL code for many years.
|
||||||
|
|
||||||
|
Major changes in this release:
|
||||||
|
|
||||||
|
Write-ahead Log(WAL) - To maintain database consistency in case
|
||||||
|
of an operating system crash, previous releases of PostgreSQL have
|
||||||
|
forced all data modifications to disk before each transaction commit.
|
||||||
|
With WAL, only one log file must be flushed to disk, greatly improving
|
||||||
|
performance. If you have been using -F in previous releases to disable
|
||||||
|
disk flushes, you may want to consider discontinuing its use.
|
||||||
|
|
||||||
|
TOAST - Previous releases had an 8k (or 32k) row length limit.
|
||||||
|
This limit made storage of long text fields difficult. With TOAST, long
|
||||||
|
rows of any length can be stored with good performance.
|
||||||
|
|
||||||
|
Outer Joins - We now support outer joins. The UNION/NOT IN
|
||||||
|
workaround for outer joins is no longer required. We use the SQL92
|
||||||
|
outer join syntax.
|
||||||
|
|
||||||
|
Function Manager - The previous C function manager did not
|
||||||
|
handle NULLs properly, nor did it support 64-bit CPU's. The new
|
||||||
|
function manager does. You can continue using your old custom
|
||||||
|
functions, but you may want to rewrite them in the future to use the new
|
||||||
|
function manager call interface.
|
||||||
|
|
||||||
|
Complex Queries - A large number of complex queries that were
|
||||||
|
unsupported in previous releases now work. Many combinations of views,
|
||||||
|
aggregates, UNION, LIMIT, cursors, subqueries, and inherited tables
|
||||||
|
now work properly. Inherited tables are now accessed by default.
|
||||||
|
Subqueries in FROM are now supported.
|
||||||
|
|
||||||
|
Migration to v7.0
|
||||||
|
|
||||||
|
A dump/restore using pg_dump is required for those wishing to migrate
|
||||||
|
data from any previous release.
