initlocation

Name

initlocation -- Create a secondary Postgres database storage area

Synopsis

initlocation directory

Description

initlocation creates a new Postgres secondary database storage area. See the discussion under CREATE DATABASE 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.

Usage

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:
$ initlocation PGDATA2
$ createdb -D PGDATA2 testdb

Alternatively, if you allow absolute paths you could write:

$ initlocation /opt/postgres/data
$ createdb -D /opt/postgres/data/testdb testdb
