At most one of <varname>recovery_target</>,
<varname>recovery_target_name</>, <varname>recovery_target_time</>, or
<varname>recovery_target_xid</> can be used; if more than one of these
is specified in the configuration file, the last entry will be used.

This parameter specifies the LSN of the transaction log location up
to which recovery will proceed. The precise stopping point is also
influenced by <xref linkend="recovery-target-inclusive">. This
parameter is parsed using the system data type
<link linkend="datatype-pg-lsn"><type>pg_lsn</></link>.
