NAME
DROP_COLLATION - remove a collation
SYNOPSIS
DROP COLLATION [ IF EXISTS ] name [ CASCADE | RESTRICT ]
DESCRIPTION
DROP COLLATION removes a previously defined collation. To be able to
drop a collation, you must own the collation.
PARAMETERS
IF EXISTS
Do not throw an error if the collation does not exist. A notice is
issued in this case.
name
The name of the collation. The collation name can be
schema-qualified.
CASCADE
Automatically drop objects that depend on the collation, and in
turn all objects that depend on those objects (see Section 5.13,
"Dependency Tracking", in the documentation).
RESTRICT
Refuse to drop the collation if any objects depend on it. This is
the default.
EXAMPLES
To drop the collation named german:
DROP COLLATION german;
COMPATIBILITY
The DROP COLLATION command conforms to the SQL standard, apart from the
IF EXISTS option, which is a PostgreSQL extension.
