Defining PostgreSQL Collations

The following properties are applicable to a PostgreSQL Collation object.

Tab	Section	Property	Description	Additional Information
		Name	Specifies the name of the collation
		Schema	Specifies the schema options for the schema generation	Select the schema from the drop-down list or click to create a new object.
		If Not Exists	Specifies that if the collation already exists, no exception is thrown, and no action happens
		Generate	Specifies whether a SQL statement for the collation is generated during forward engineering
General	General Options	Locale	Specifies the local name of the collation	This shortcut simultaneously sets LC_COLLATE and LC_CTYPE. If you use this option, you cannot individually specify either parameter.
		LC_Collate	Specifies that the LC_COLLATE locale category should use the specified operating system locale. The locale must apply to the current database encoding.
		LC_CType	Specifies that the LC_CTYPE locale category should use the specified operating system locale. The locale must apply to the current database encoding.
		Provider	Specifies the provider to use for locale services associated with this collation. Possible values are icu (if the server was built with ICU support) or libc. libc is the default.	Icu: Indicates the advanced, consistent, and locale-aware collation rules based on Unicode, suitable for diverse and multi-language sorting. Libc: Indicates the collation rules based on the operating system's C library, with behavior that can vary and may be less flexible compared to ICU.
		Is Deterministic	Specifies whether the collation should use deterministic comparisons
		ICU Rules	Specifies additional collation rules to customize the behavior of the collation. The ICU only supports this feature.
		Version	Specifies the version string to store with the collation
	Copy Options	Copy Collation	Specifies the name of an existing collation to copy. The new collation will have the same properties as the existing one but will be an independent object.
