SYNOPSIS
-
gfdump.postgresql -d [options]
- gfdump.postgresql -r [options]
DESCRIPTION
gfdump.postgresql
When gfdump.postgresql is executed with -d option, it dumps the database to the file db.out at the current directory.
When it is executed with -r option, it restores the database from the dump file, db.out at the current directory. More specifically, it does the followings.
- 1. Stop gfmd if running.
- 2. Remove the current database.
- 3. Create a database again.
- 4. Restore a database from the dump file.
- 5. Delete the current journal file of gfmd, if exists.
- 6. Start gfmd again.
OPTIONS
--prefix path
- If this option is given, gfdump.postgresql reads PREFIX/etc/gfmd.conf as the configuration file of gfmd. By default, it reads %%SYSCONFDIR%%/etc/gfmd.conf.
-P prefix
- Specify an installation prefix of the backend database (e.g. /usr/local). When gfdump.postgresql executes a PostgreSQL command such as pg_dump, it assumes the command is installed under the given prefix. If this option is omitted, gfdump.postgresql searches directories listed in the environment variable PATH for the commands.
-l
-
Specify a path to the directory where the backend database puts files to store metadata of Gfarm.
If the backend database is PostgreSQL, the directory is commonly called PGDATA directory. The default is PREFIX/var/gfarm-pgsql where PREFIX is a prefix given by --prefix option.
-f file
- Specify the name of dump file. The default is db.out at the current directory.

- Show usage, then exit.
-t
- Show values of configurable parameters in human readable format, then exit immediately.
