Changes
SQL Features
-
- Modify the definition of window-function PARTITION
- BY and ORDER BY clauses so that their elements are always
- taken as simple expressions over the query's input
- columns.
-
-
- Fix bug with WITH RECURSIVE immediately inside WITH
- RECURSIVE.
-
-
-
- Define a new, more extensible syntax for COPY options.
-
-
-
- Add ALTER DEFAULT PRIVILEGES command, which allows
- users to adjust the privileges that will be applied to
- subsequently-created objects.
+ Add SQL-compliant triggers on columns, which fire only if
+ certain columns are named in the UPDATE's SET list.
- Support use of function argument names to identify which
- actual arguments match which function parameters. The syntax
- uses AS, for example funcname(value AS arg1, anothervalue AS
- arg2).
+ Add CREATE LIKE INCLUDING COMMENTS and STORAGE, and INCLUDING
+ ALL shortcut to allow users to make an exact copy of a table including
+ all options and features.
- Add CREATE LIKE INCLUDING COMMENTS and STORAGE, and INCLUDING
- ALL shortcut.
+ Define a new, more extensible syntax for COPY options
+ in order to support additional COPY options in the future.
- Add GRANT/REVOKE ON ALL TABLES/SEQUENCES/FUNCTIONS IN SCHEMA.
+ Modify the definition of window-function PARTITION
+ BY and ORDER BY clauses so that their elements are always
+ taken as simple expressions over the query's input
+ columns. This fixes a bug.
- Add SQL-compliant triggers on columns, ie fire only if
- certain columns are named in the UPDATE's SET list.
+ Fix bug with nested WITH RECURSIVE statements.
Implement "join removal" for cases where the inner side
- of a left join is unique and is not referenced above the join.
+ of a left join is unique and is not referenced above the join. This should
+ speed up many ORM-generated and reporting tool queries.
+
+
+
+ Remove the use of the flat files pg_auth and
+ pg_database in order to improve performance. (Warning: pgbouncer
+ and possibly other tools currently suggest referring to the pg_auth
+ file for its user database. Such schemes will no longer work.)
Make it possibly to specify server configuration parameters
- per user and per database. psql has gained a drds command to
+ per user-database combination. Add a \drds command to psql to
display the settings.
Allow the collection of statistics on sequences.
+
+ Increase the maximum value of extra_float_digits to
+ 3, and have pg_dump use that value when the backend is new
+ enough to allow it, because it is possible to need 3 extra
+ digits for float4 values (but not for float8 values).
+
+
Add the ability to include the SQLSTATE error code of any error

+ raising limits on keys and values, conversions to and from
+ records and arrays, and support for GROUP BY and DISTINCT.
