A new <TT CLASS="COMMAND" >VACUUM FULL</TT > command does old-style vacuum by locking the table and shrinking the on-disk copy of the table. </P ></DD ><DT >Transactions</DT ><DD ><P > There is no longer a problem with installations that exceed four billion transactions. </P ></DD ><DT >OIDs</DT ><DD ><P > OIDs are now optional. Users can now create tables without OIDs for cases where OID usage is excessive. </P ></DD ><DT >Optimizer</DT ><DD ><P > The system now computes histogram column statistics during <TT CLASS="COMMAND" >ANALYZE</TT >, allowing much better optimizer choices. </P ></DD ><DT >Security</DT ><DD ><P > A new MD5 encryption option allows more secure storage and transfer of passwords. A new Unix-domain socket authentication option is available on Linux and BSD systems. </P ></DD ><DT >Statistics</DT ><DD ><P > Administrators can use the new table access statistics module to get fine-grained information about table and index usage. </P ></DD ><DT >Internationalization</DT ><DD ><P > Program and library messages can now be displayed in several languages. </P ></DD ></DL ></DIV ></DIV ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="AEN144959" >E.258.2. Migration to Version 7.2</A ></H2 ><P > A dump/restore using <TT CLASS="COMMAND" >pg_dump</TT > is required for those wishing to migrate data from any previous release. </P ><P > Observe the following incompatibilities: </P ><P ></P ><UL ><LI ><P > The semantics of the <TT CLASS="COMMAND" >VACUUM</TT > command have changed in this release. You might wish to update your maintenance procedures accordingly. </P ></LI ><LI ><P > In this release, comparisons using <TT CLASS="LITERAL" >= NULL</TT > will always return false (or NULL, more precisely). Previous releases automatically transformed this syntax to <TT CLASS="LITERAL" >IS NULL</TT >.

You will need to rewrite your applications. </P ></LI ><LI ><P > The <TT CLASS="LITERAL" >timestamp()</TT >, <TT CLASS="LITERAL" >time()</TT >, and <TT CLASS="LITERAL" >interval()</TT > functions are no longer available.
