There's a small typo in the first paragraph, "paramater" should be
"parameter":

diff --git a/doc/src/sgml/recovery-config.sgml
b/doc/src/sgml/recovery-config.sgml
new file mode 100644
index ee5dc86..550cdce
*** a/doc/src/sgml/recovery-config.sgml

*** 152,158 ****
By default, a standby server keeps restoring WAL records from the
primary as soon as possible. It may be useful to have a
time-delayed
copy of the data, offering various options to correct data loss
errors.
! This paramater allows you to delay recovery by a fixed period of
time,
specified in milliseconds if no unit is specified. For example,
if
you set this parameter to <literal>5min</literal>, the standby
will
replay each transaction commit only when the system time on the
standby
