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 --- b/doc/src/sgml/recovery-config.sgml *************** restore_command = 'copy "C:\\server\\arc *** 152,158 **** By default, a standby server keeps restoring WAL records from the primary as soon as possible.
