It is also possible to use <productname>Slony</> to create a slave
server with the updated version of <productname>PostgreSQL</>. The
slave can be on the same computer or a different computer. Once it
has synced up with the master server (running the older version of
<productname>PostgreSQL</>), you can switch masters and make the slave
the master and shut down the older database instance. Such a
switch-over results in only several seconds of downtime for an upgrade.
It is also possible to use replication like <productname>Slony</> to
create a slave server with the updated version of
<productname>PostgreSQL</>. The slave can be on the same computer or
a different computer. Once it has synced up with the master server
(running the older version of <productname>PostgreSQL</>), you can
switch masters and make the slave the master and shut down the older
database instance. Such a switch-over results in only several seconds
