SYNOPSIS

       DROP INDEX index_name [, ...] [ CASCADE | RESTRICT ]

   INPUTS
       index_name
	      The name (optionally schema-qualified) of an index to remove.

       CASCADE
	      Automatically drop objects that depend on the index.

       RESTRICT
	      Refuse to drop the index if there are any dependent objects.  This is the default.

   OUTPUTS

       ERROR: index "index_name" does not exist
	      This message occurs if index_name is not an index in the database.

DESCRIPTION

       DROP INDEX drops an existing index from the database system. To execute this command you must be the owner of the index.

   NOTES
       DROP INDEX is a PostgreSQL language extension.

       Refer to CREATE INDEX [create_index(7)] for information on how to create indexes.

USAGE

       This command will remove the title_idx index:

	   DROP INDEX title_idx;

COMPATIBILITY

   SQL92
       SQL92  defines  commands by which to access a generic relational database.  Indexes are an implementation-dependent feature and hence there
       are no index-specific commands or definitions in the SQL92 language.
