NAME
       SELECT_INTO - define a new table from the results of a query

SYNOPSIS
       [ WITH [ RECURSIVE ] with_query [, ...] ]
       SELECT [ ALL | DISTINCT [ ON ( expression [, ...] ) ] ]
           * | expression [ [ AS ] output_name ] [, ...]
           INTO [ TEMPORARY | TEMP | UNLOGGED ] [ TABLE ] new_table
           [ FROM from_item [, ...] ]
           [ WHERE condition ]
           [ GROUP BY expression [, ...] ]
           [ HAVING condition ]
           [ WINDOW window_name AS ( window_definition ) [, ...] ]
           [ { UNION | INTERSECT | EXCEPT } [ ALL | DISTINCT ] select ]
           [ ORDER BY expression [ ASC | DESC | USING operator ] [ NULLS { FIRST | LAST } ] [, ...] ]
           [ LIMIT { count | ALL } ]
           [ OFFSET start [ ROW | ROWS ] ]
           [ FETCH { FIRST | NEXT } [ count ] { ROW | ROWS } ONLY ]
           [ FOR { UPDATE | SHARE } [ OF table_name [, ...] ] [ NOWAIT ] [...] ]

DESCRIPTION
       SELECT INTO creates a new table and fills it with data computed by a query. The data is
       not returned to the client, as it is with a normal SELECT. The new table's columns have
       the names and data types associated with the output columns of the SELECT.

PARAMETERS
       TEMPORARY or TEMP
           If specified, the table is created as a temporary table. Refer to CREATE TABLE
           (CREATE_TABLE(7)) for details.

       UNLOGGED
           If specified, the table is created as an unlogged table. Refer to CREATE TABLE
           (CREATE_TABLE(7)) for details.

       new_table
           The name (optionally schema-qualified) of the table to be created.

       All other parameters are described in detail under SELECT(7).

NOTES
       CREATE TABLE AS (CREATE_TABLE_AS(7)) is functionally similar to SELECT INTO.  CREATE TABLE
       AS is the recommended syntax, since this form of SELECT INTO is not available in ECPG or
       PL/pgSQL, because they interpret the INTO clause differently. Furthermore, CREATE TABLE AS
       offers a superset of the functionality provided by SELECT INTO.

       In contrast to CREATE TABLE AS, SELECT INTO does not allow specifying properties like a
       table's access method with USING method or the table's tablespace with TABLESPACE
       tablespace_name. Use CREATE TABLE AS (CREATE_TABLE_AS(7)) if necessary. Therefore, the
       default table access method is chosen for the new table. See default_table_access_method
       for more information.

EXAMPLES
       Create a new table films_recent consisting of only recent entries from the table films:

           SELECT * INTO films_recent FROM films WHERE date_prod >= '2002-01-01';

COMPATIBILITY
       The SQL standard uses SELECT INTO to represent selecting values into scalar variables of a
       host program, rather than creating a new table. This indeed is the usage found in ECPG
       (see Chapter 35) and PL/pgSQL (see Chapter 42). The PostgreSQL usage of SELECT INTO to
       represent table creation is historical. It is best to use CREATE TABLE AS for this purpose
       in new code.
