* Disallow function-style and attribute-style data type casts for
58
60
composite types (Tom Lane)
59
61
For example, disallow composite_value.text and
60
text(composite_value). The CAST and :: syntaxes are still available
61
for use when a cast of an entire composite value is actually
62
text(composite_value). Unintentional uses of this syntax have
63
frequently resulted in bug reports; although it was not a bug, it
64
seems better to go back to rejecting such expressions. The CAST and
65
:: syntaxes are still available for use when a cast of an entire
66
composite value is actually intended.

* Tighten casting checks for domains based on arrays (Tom Lane)

When a domain is based on an array type, it is allowed to "look
65
69
through" the domain type to access the array elements, including
68
72
UPDATE ... SET domaincol[5] = ..., will now result in rechecking
69
73
the domain type's constraints, whereas before the checks were

Also, such a domain type is no longer allowed to match an anyarray

parameter of a polymorphic function, except by explicitly
73
downcasting it to the base array type.

Object Modification

111
by the attached exception block (Piyush Newe)

112
Previously RAISE in a code block was always scoped to an attached
112
113
exception block, so it was uncatchable at the same scope.

* Adjust PL/pgSQL's error line reporting code to be consistent with
114
* Adjust PL/pgSQL's error line numbering code to be consistent with
114
115
other PLs (Pavel Stehule)
115
116
Previously, PL/pgSQL would ignore (not count) an empty line at the
116
117
start of the function body. Since this was inconsistent with all
117
118
other languages, the special case was removed.
119
* Make PL/pgSQL complain about conflicting IN and OUT parameter names
121
Formerly, the collision was not detected, and the name would just
122
silently refer to only the OUT parameter.
123
* Type modifiers of PL/pgSQL variables are now visible to the SQL
125
A type modifier (such as a varchar length limit) attached to a
126
PL/pgSQL variable was formerly enforced during assignments, but was
127
ignored for all other purposes. Such variables will now behave more
128
like table columns declared with the same modifier. This is not
129
expected to make any visible difference in most cases, but it could
130
result in subtle changes for some SQL commands issued by PL/pgSQL

Such tables provide better update performance than regular tables,

either side of a LEFT OUTER JOIN or RIGHT OUTER JOIN to be hashed

* Allow inheritance table queries to return meaningfully-sorted

This allows optimization of ORDER BY and LIMIT clauses in

inheritance table queries.

Formerly, such lines were silently ignored, which could be

surprising. This makes the behavior more like other unsupported

* Allow GSSAPI to be used to authenticate to servers via SSPI

Specifically this allows Unix-based GSSAPI clients to do SSPI
182
201
authentication with Windows servers.
202
* ident authentication over local sockets is now known as peer
204
The old term is still accepted for backward compatibility.
205
* Rewrite peer authentication to avoid use of credential control
207
This change makes the peer authentication code simpler and
208
better-performing. However, it requires the platform to provide the
209
getpeereid function or an equivalent socket operation. So far as is
210
known, the only platform for which peer authentication worked
211
before and now will not is pre-5.0 NetBSD.

334
This allows external cluster management software to take control of

whether servers restart or not.

Some other database system already allowed this behavior, and

Urbanski, Heikki Linnakangas)

table, or a typed table to be made standalone.

731
trying to open a new session.

* Add extensions which simplify packaging of additions to PostgreSQL
684
(Dimitri Fontaine, Tom Lane)
685
This is controlled by the new "CREATE"/"ALTER"/"DROP EXTENSION "
686
command; this replaces a more manual method of adding features to
742
* Use +Olibmerrno compile flag with HP-UX C compilers that accept it
744
This avoids possible misbehavior of math library calls on recent HP
688

* Improved parallel make support (Peter Eisentraut)
693
This allows for faster compiles. Also, make "-k" and make "-q" now
694
work properly in a parallel build.
751
This allows for faster compiles. Also, make -k now works more
695
753
* Require GNU make 3.80 or newer (Peter Eisentraut)
696
754
This is necessary because of the parallel-make improvements.
755
* Add make maintainer-check target (Peter Eisentraut)
756
This target performs various source code checks that are not
757
appropriate for either the build or the regression tests.
758
Currently: duplicate_oids, SGML syntax and tabs check, NLS syntax
760
* Support make check in "contrib" (Peter Eisentraut)
761
Formerly only make installcheck worked, but now there is support
762
for testing in a temporary installation. The top-level make
763
check-world target now includes testing "contrib" this way.

minidumps can now be generated by non-debug Windows binaries and
706
773
analyzed by standard debugging tools.
707
* Enable building with the Mingw64 compiler (Andrew Dunstan)
774
* Enable building with the MinGW64 compiler (Andrew Dunstan)
708
775
This allows building 64-bit Windows binaries even on non-Windows
709
platforms with cross-compiling.

* Revise the API for GUC variable assign hooks (Tom Lane)
782
The previous functions of assign hooks are now split between check
783
hooks and assign hooks, where the former can fail but the latter
784
shouldn't. This change will impact add-on modules that define
785
custom GUC parameters.
714
786
* Add latches to the source code to wait for events (Heikki
716
788
* Centralize data modification permissions-checking logic (KaiGai

* Add missing get_{object}_oid() functions, for consistency (Robert

* Improve ability to use C++ compilers for backend compiles by
721
removing conflicting keywords (Tom Lane)
792
* Improve ability to use C++ compilers for compiling add-on modules
793
by removing conflicting key words (Tom Lane)
722
794
* Add support for DragonFly BSD (Rumko)
723
795
* Expose quote_literal_cstr() for backend use (Robert Haas)
724
796
* Run regression tests in the default encoding (Peter Eisentraut)
744
* Modify "/contrib" modules and stored procedure languages to install
816
* Modify "contrib" modules and stored procedure languages to install
745
817
via the new extension mechanism (Tom Lane, Dimitri Fontaine)
746
This replaces a more manual method of installation.
747
818
* Add "contrib/file_fdw" foreign-data wrapper (Shigeru Hanada)
748
819
Foreign tables using this foreign data wrapper can read flat files
749
820
in a manner very similar to "COPY".
751
822
"contrib/btree_gist" (Teodor Sigaev)
752
823
* Add "contrib/btree_gist" support for searching on not-equals (Jeff
754
* Allow "contrib/fuzzystrmatch"'s levenshtein() function handle
755
multi-byte characters (Alexander Korotkov)
825
* Fix "contrib/fuzzystrmatch"'s levenshtein() function to handle
826
multibyte characters (Alexander Korotkov)
756
827
* Add ssl_cipher() and ssl_version() functions to "contrib/sslinfo"
758
829
* Fix "contrib/intarray" and "contrib/hstore" to give consistent
759
830
results with indexed empty arrays (Tom Lane)
760
831
Previously an empty-array query that used an index might return
761
832
different results from one that used a sequential scan.
762
* Allow "contrib/intarray" to work properly on multi-dimensional
833
* Allow "contrib/intarray" to work properly on multidimensional
763
834
arrays (Tom Lane)
764
835
* In "contrib/intarray", avoid errors complaining about the presence
765
836
of nulls in cases where no nulls are actually present (Tom Lane)
821
892
* Add documentation for exit_on_error (Robert Haas)
822
893
This parameter causes sessions to exit on any error.
823
894
* Add documentation for pg_options_to_table() (Josh Berkus)
824
This parameter shows table storage options.
825
* Document that it is possible to access all composite fields using
826
(compositeval).* syntax (Peter Eisentraut)
895
This function shows table storage options in a readable form.
896
* Document that it is possible to access all composite type fields
897
using (compositeval).* syntax (Peter Eisentraut)
827
898
* Document that translate() removes characters in from that don't
