Pivotal Greenplum GPText v2.2.1

GPText Configuration Parameters

GPText configuration parameters can be overridden by setting a new value in a Greenplum Database session. Changes made to configuration parameters only affect future GPText operations; existing indexes use the parameter values that were set when they were created.

See Changing GPText Server Configuration Parameters for information about changing configuration parameters and examples.

The following table lists the GPText configuration parameters with their defaults and value constraints.
