Examples To create a unique B-tree index on the column title in the table films: CREATE UNIQUE INDEX title_idx ON films (title); To create a unique B-tree index on the column title with included columns director and rating in the table films: CREATE UNIQUE INDEX title_idx ON films (title) INCLUDE (director, rating); To create a B-Tree index with deduplication disabled: CREATE INDEX title_idx ON films (title) WITH (deduplicate_items = off); To create an index on the expression lower(title), allowing efficient case-insensitive searches: CREATE INDEX ON films ((lower(title))); (In this example we have chosen to omit the index name, so the system will choose a name, typically films_lower_idx.) To create an index with non-default collation: CREATE INDEX title_idx_german ON films (title COLLATE "de_DE"); To create an index with non-default sort ordering of nulls: CREATE INDEX title_idx_nulls_low ON films (title NULLS FIRST); To create an index with non-default fill factor: CREATE UNIQUE INDEX title_idx ON films (title) WITH (fillfactor = 70); To create a GIN index with fast updates disabled: CREATE INDEX gin_idx ON documents_table USING GIN (locations) WITH (fastupdate = off); To create an index on the column code in the table films and have the index reside in the tablespace indexspace: CREATE INDEX code_idx ON films (code) TABLESPACE indexspace; To create a GiST index on a point attribute so that we can efficiently use box operators on the result of the conversion function: CREATE INDEX pointloc ON points USING gist (box(location,location)); SELECT * FROM points WHERE box(location,location) && '(0,0),(1,1)'::box; To create an index without locking out writes to the table: CREATE INDEX CONCURRENTLY sales_quantity_index ON sales_table (quantity); Compatibility CREATE INDEX is a PostgreSQL language extension.
