Other Default Parameters

This section describes the default database loading parameters of the database system.

dynamic_library_path

Parameter description: Specifies the path for saving the shared database files that are dynamically loaded for data searching. When a dynamically loaded module needs to be opened and the file name specified in the CREATE FUNCTION or LOAD command does not have a directory component, the system will search this path for the required file.

The value of dynamic_library_path must be a list of absolute paths separated by colons (:) or by semi-colons (;) on the Windows OS. The special variable $libdir in the beginning of a path will be replaced with the module installation directory provided by GaussDB(DWS). Example:
1
dynamic_library_path = '/usr/local/lib/postgresql:/opt/testgs/lib:$libdir'

Type: SUSET

Value range: a string

If the value of this parameter is set to an empty character string, the automatic path search is turned off.

Default value: $libdir

gin_fuzzy_search_limit

Parameter description: Specifies the upper limit of the size of the set returned by GIN indexes.

Type: USERSET

Value range: an integer ranging from 0 to INT_MAX. The value 0 indicates no limit.

Default value: 0
