<title>SQL99 Feature List

<appendix id="features">
<title>SQL Conformance
</title>
<para>
<acronym>SQL92</acronym> defined three feature sets for
compliance: basic, intermediate, and advanced. Most database
products claiming <acronym>SQL</acronym> standards compliance were
compliant at only the basic level, since the entire set of
intermediate and advanced features was either too voluminous or in
This section attempts to outline to what extent
<productname>PostgreSQL</productname> conforms to the SQL standard.
Full compliance to the standard or a complete statement about the
compliance to the standard is complicated and not particularly
useful, so this section can only give an overview.
</para>
<para>
The formal name of the SQL standard is ISO/IEC 9075 <quote>Database
Language SQL</quote>. A revised version of the standard is released
from time to time; the most recent one appearing in 1999. That
version is refered to as ISO/IEC 9075:1999, or informally as SQL99.
The version prior to that was SQL92.
<productname>PostgreSQL</productname> development tends to aim for
conformance with the latest official version of the standard where
such conformance does not contradict traditional features or common
sense. At the time of this writing, ballotting is under way for a
new revision of the standard, which, if approved, will eventually
become the conformance target for future
<productname>PostgreSQL</productname> development.
</para>
<para>
<acronym>SQL92</acronym> defined three feature sets for conformance:
Entry, Intermediate, and Full. Most database products claiming
<acronym>SQL</acronym> standard conformance were conforming at only
the Entry level, since the entire set of features in the
Intermediate and Full levels was either too voluminous or in
conflict with legacy behaviors.
</para>
<para>
<acronym>SQL99</acronym> defines a large set of individual features
rather than the ineffectively broad three levels found in
<acronym>SQL92</acronym>. We provide a list of supported features,
followed by a list of the features defined in
<acronym>SQL99</acronym> which are not yet supported in
<productname>PostgreSQL</>.
<acronym>SQL92</acronym>. A large subset of these features
represents the <quote>core</quote> features, which every conforming
SQL implementation must supply. The rest of the features are purely
optional. Some optional features are grouped together to form
<quote>packages</quote>, which SQL implementations can claim
conformance to, thus claiming conformance to particular groups of
features.
</para>
<para>
The <acronym>SQL99</acronym> standard is also split into 5 parts:
Framework, Foundation, Call Level Interface, Persistent Stored
Modules, and Host Language Bindings.
<productname>PostgreSQL</productname> only covers parts 1, 2, and 5.
Part 3 is similar to the ODBC interface, and part 4 is similar to
the <application>PL/pgSQL</application> programming language, but
exact conformance is not specifically intended in either case.
</para>
<para>
In the following two sections, we provide a list of those features
that <productname>PostgreSQL</productname> supports, followed by a
list of the features defined in SQL99 which are not yet supported in
PostgreSQL. Both of these lists are approximate: There may be minor
details that are nonconforming for a feature that is listed as
supported, and large parts of an unsupported feature may in fact be
implemented. The main body of the documentation always contains the
most accurate information about what does and does not work.
</para>
<note>
<para>
Feature codes containing a hyphen are subfeatures. Therefore, if a
particular subfeature is not supported, the main feature is listed
as unsupported even if some other subfeatures are supported.
