<para>

<productname>PostgreSQL</productname> covers parts 1, 2, 11, and 14.

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 or verified in either

case.

The <productname>PostgreSQL</productname> core covers parts 1, 2,

11, and 14. Part 3 is covered by the ODBC driver, and part 13 is

covered by the PL/Java plug-in, but exact conformance is currently

not being verified for these components. There are currently no

implementations of parts 4, 9, and 10

for <productname>PostgreSQL</productname>.
