NAME

       DROP TYPE - remove a user-defined data type

SYNOPSIS

       DROP TYPE typename [, ...] [ CASCADE | RESTRICT ]

   INPUTS
       typename
	      The name (optionally schema-qualified) of an existing type.

       CASCADE
	      Automatically drop objects that depend on the type (such as table columns, functions, operators, etc).

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

   OUTPUTS
       DROP TYPE
	      The message returned if the command is successful.

       ERROR: RemoveType: type 'typename' does not exist
	      This message occurs if the specified type is not found.

DESCRIPTION

       DROP TYPE will remove a user type from the system catalogs.

       Only the owner of a type can remove it.

EXAMPLES

       To remove the box type:

       DROP TYPE box;

COMPATIBILITY

       Note that the CREATE TYPE command and the data type extension mechanisms in PostgreSQL differ from SQL99.

NAME

       DROP INDEX - remove an index

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
       DROP INDEX
	      The message returned if the command completes successfully.

       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.
