Column Name Data Type Description
NODE_NAME VARCHAR

Node names of the database cluster.

ALL indicates that all nodes have the same value.

PARAMETER_NAME VARCHAR The parameter name.
CURRENT_VALUE VARCHAR The parameter's current setting.
RESTART_VALUE VARCHAR The parameter's value after the next restart.
DATABASE_VALUE VARCHAR The value that is set at the database level. If no database-level value is set, the value reflects the default value.
DEFAULT_VALUE VARCHAR The parameter's default value.
CURRENT_LEVEL VARCHAR

Level at which CURRENT_VALUE is set, one of the following:

  • NODE

  • DATABASE

  • SESSION

  • DEFAULT

RESTART_LEVEL VARCHAR

Level at which the parameter will be set after the next restart, one of the following:

  • NODE

  • DATABASE

  • DEFAULT

IS_MISMATCH BOOLEAN Whether CURRENT_VALUE and RESTART_VALUE match.
GROUPS VARCHAR

A group to which the parameter belongs—for example, OptVOptions.

ALLOWED_LEVELS VARCHAR

Levels at which the specified parameter can be set, a comma-delimited list of any of the following values:

  • DATABASE

  • NODE

  • SESSION

  • USER

SUPERUSER_VISIBLE_ONLY BOOLEAN

Whether non-superusers can view all parameter settings. If true, the following columns are masked to non-superusers:

  • CURRENT_VALUE

  • RESTART_VALUE

  • DATABASE_VALUE

  • DEFAULT_VALUE

CHANGE_UNDER_SUPPORT_GUIDANCE BOOLEAN Whether the parameter is intended for use only under guidance from customer support.
CHANGE_REQUIRES_RESTART BOOLEAN Whether the configuration change requires a restart.
DESCRIPTION VARCHAR Describes the parameter's usage.

Examples

The following example shows a case where the parameter requires a restart for the new setting to take effect:

=> SELECT * FROM CONFIGURATION_PARAMETERS WHERE parameter_name = 'RequireFIPS';
-[ RECORD 1 ]-----------------+----------------------

The following example shows a case where a non-superuser is viewing a parameter with restricted visibility:

=> \c VMart nonSuperuser
You are now connected to database "VMart" as user "nonSuperuser".
=> SELECT * FROM CONFIGURATION_PARAMETERS WHERE superuser_visible_only = 't';
