switchover
==========

Switches over to new write leader.

Synopsis
^^^^^^^^

Switches over to new write leader. Use switchover method ‘fast’ for
immediate switchover. Use ‘strict’ to wait until lag is less than
‘route_writer_max_lag’ on the given target node. If switchover fails due
to timeout or any other issue, BDR might elect a write leader that’s
different from the given target node.

.. code:: sh

   pgd switchover [flags]

Examples
^^^^^^^^

.. code:: text


     Example 1 (with required arguments, default method is strict and default
     timeout is 10s)

     $ pgd switchover --group-name group_a --node-name bdr-a1
     switchover is complete

     Example 2 (with optional arguments)

     $ pgd switchover --group-name group_a --node-name bdr-a1 --method strict --timeout 15s
     switchover is complete

     Example 3 (immediate switchover)

     $ pgd switchover --group-name group_a --node-name bdr-a1 --method fast
     switchover is complete
