Description
- creates a new
PostgreSQL secondary database storage area.
- See the discussion under
- about how to manage and use secondary storage areas. If the argument does not contain
- a slash and is not valid as a path, it is assumed to be an environment variable,
- which is referenced. See the examples at the end.
-
- In order to use this command you must be logged in (using su, for example)
- as the database superuser.
-
-
-
-
-
Examples
-
- To create a database in an alternate location, using an
- environment variable:
-
-
$ export PGDATA2=/opt/postgres/data-
- Stop and start postmaster so it sees the PGDATA2
- environment variable. The system must be configured so the
- postmaster sees PGDATA2 every time it starts. Finally:
-
-
$ createdb -D PGDATA2 testdb-
-
-
- Alternatively, if you allow absolute paths you could write:
-
-
$ initlocation /opt/postgres/data-
$ createdb -D /opt/postgres/data/testdb testdb-
