NAME

       DROP SEQUENCE - remove a sequence

SYNOPSIS

       DROP SEQUENCE name [, ...] [ CASCADE | RESTRICT ]

   INPUTS
       name   The name (optionally schema-qualified) of a sequence.

       CASCADE
	      Automatically drop objects that depend on the sequence.

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

   OUTPUTS
       DROP SEQUENCE
	      The message returned if the sequence is successfully dropped.

       ERROR: sequence "name" does not exist
	      This message occurs if the specified sequence does not exist.

DESCRIPTION

       DROP  SEQUENCE  removes	sequence  number  generators from the data base. With the current implementation of sequences as special tables it
       works just like the DROP TABLE statement.

   NOTES
       The DROP SEQUENCE statement is a PostgreSQL language extension.

       Refer to the CREATE SEQUENCE statement for information on how to create a sequence.

USAGE

       To remove sequence serial from database:

       DROP SEQUENCE serial;

COMPATIBILITY

   SQL92
       There is no DROP SEQUENCE in SQL92.

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.
