tablefunc
The tablefunc module provides various functions that return tables (that is, multiple rows).
The Greenplum Database tablefunc module is equivalent to the PostgreSQL tablefunc module. There are no Greenplum Database or MPP-specific considerations for the module.
Installing and Registering the Module
The tablefunc module is installed when you install Greenplum Database. Before you can use any of the functions defined in the module, you must register the tablefunc extension in each database in which you want to use the functions:
