fuzzystrmatch module provides functions to determine similarities and distance between strings based on various algorithms.
The Greenplum Database
fuzzystrmatch module is equivalent to the PostgreSQL
fuzzystrmatch module. There are no Greenplum Database or MPP-specific considerations for the module.
fuzzystrmatch module is installed when you install Greenplum Database. Before you can use any of the functions defined in the module, you must register the
fuzzystrmatch extension in each database in which you want to use the functions. Refer to Installing Additional Supplied Modules for more information.
See fuzzystrmatch in the PostgreSQL documentation for detailed information about the individual functions in this module.
