SYNOPSIS

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.
