The 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.
The 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.
