Operating system: n/a
Description: Doc Clarification: archive_command and restore_command
When describing archive_command and restore_command (Chapter 23 - Backup and
Restore), the replacement strings '%p' and '%f' are explained:
"In this string, any %p is replaced by the path name of the file to archive,
while any %f is replaced by the file name only."
The description of %p is misleading since it is replaced with not just the
path, but also filename. The way it is written now, one might expect the
string "%p/%f" to resolve to the full path and filename of the file.
However, "%p" is sufficient.
A small change in the sentence would clarify:
"In this string, any %p is replaced by the full path and file name of the
file to archive, while any %f is replaced by the file name only."
An example showing how the sample commands would be expanded would also
The simplest useful command is something like
archive_command = 'cp -i %p /mnt/server/archivedir/%f </dev/null'
The above example might be expanded to
cp -i /var/lib/postgresql/8.2/main/pgdata/pg_xlog/00000001000000A900000065
