Greenplum Environment Variables

    Set these in your user’s startup shell profile (such as or ~/.bash_profile), or in /etc/profile if you want to set them for all users.

    Note: GPHOME, PATH and LD_LIBRARY_PATH can be set by sourcing the greenplum_path.sh file from your Greenplum Database installation directory

    This is the installed location of your Greenplum Database software. For example:

    PATH

    LD_LIBRARY_PATH

    The LD_LIBRARY_PATH environment variable should point to the location of the Greenplum Database/PostgreSQL library files. For example:

    MASTER_DATA_DIRECTORY

    This should point to the directory created by the gpinitsystem utility in the master data directory location. For example:

    Optional Environment Variables

    The following are standard PostgreSQL environment variables, which are also recognized in Greenplum Database. You may want to add the connection-related environment variables to your profile for convenience, so you do not have to type so many options on the command line for client connections. Note that these environment variables should be set on the Greenplum Database master host only.

    PGAPPNAME

    The name of the application that is usually set by an application when it connects to the server. This name is displayed in the activity view and in log entries. The PGAPPNAME environmental variable behaves the same as the application_name connection parameter. The default value for application_name is psql. The name cannot be longer than 63 characters.

    The name of the default database to use when connecting.

    PGHOST

    The Greenplum Database master host name.

    PGHOSTADDR

    PGPASSWORD

    The password used if the server demands password authentication. Use of this environment variable is not recommended for security reasons (some operating systems allow non-root users to see process environment variables via ps). Instead consider using the ~/.pgpass file.

    PGPASSFILE

    The name of the password file to use for lookups. If not set, it defaults to ~/.pgpass. See the topic about in the PostgreSQL documentation for more information.

    Sets additional configuration parameters for the Greenplum Database master server.

    PGPORT

    The port number of the Greenplum Database server on the master host. The default port is 5432.

    PGUSER

    The Greenplum Database user name used to connect.

    PGDATESTYLE

    Sets the default style of date/time representation for a session. (Equivalent to SET datestyle TO...)

    PGTZ

    Sets the default time zone for a session. (Equivalent to SET timezone TO...)
