       INSERT - create new rows in a table

       INSERT INTO table [ ( column [, ...] ) ]
	   { DEFAULT VALUES | VALUES ( { expression | DEFAULT } [, ...] ) | query }

       INSERT  inserts	new  rows  into	 a table.  One can insert a single row
       specified by value expressions, or several rows as a result of a query.

       The target column names may be listed in any order. If no list of  col-
       umn  names is given at all, the default is all the columns of the table
       in their declared order; or the first N column names, if there are only
       N  columns  supplied by the VALUES clause or query. The values supplied
       by the VALUES clause or query  are  associated  with  the  explicit  or
       implicit column list left-to-right.

       Each column not present in the explicit or implicit column list will be
       filled with a default value, either its declared default value or  null
       if there is none.

       If the expression for any column is not of the correct data type, auto-
       matic type conversion will be attempted.

       You must have INSERT privilege to a table in order to insert  into  it.
       If  you use the query clause to insert rows from a query, you also need
       to have SELECT privilege on any table used in the query.

       table  The name (optionally schema-qualified) of an existing table.

       column The name of a column in table.  The column name can be qualified
	      with  a  subfield name or array subscript, if needed. (Inserting
	      into only some fields of a composite  column  leaves  the	 other
	      fields null.)

	      All columns will be filled with their default values.

	      An expression or value to assign to the corresponding column.

	      The corresponding column will be filled with its default value.

       query  A	 query	(SELECT	 statement)  that  supplies  the  rows	to  be
	      inserted. Refer to the SELECT statement for a description of the

       On  successful  completion,  an INSERT command returns a command tag of

       INSERT oid count

       The count is the number of rows inserted. If count is exactly one,  and
       the target table has OIDs, then oid is the OID assigned to the inserted
       row. Otherwise oid is zero.

       Insert a single row into table films:

	   ('UA502', 'Bananas', 105, '1971-07-13', 'Comedy', '82 minutes');

       In this example, the len column is omitted and therefore it  will  have
       the default value:

       INSERT INTO films (code, title, did, date_prod, kind)
	   VALUES ('T_601', 'Yojimbo', 106, '1961-06-16', 'Drama');

       This  example  uses the DEFAULT clause for the date columns rather than
       specifying a value:

	   ('UA502', 'Bananas', 105, DEFAULT, 'Comedy', '82 minutes');
       INSERT INTO films (code, title, did, date_prod, kind)
	   VALUES ('T_601', 'Yojimbo', 106, DEFAULT, 'Drama');

       To insert a row consisting entirely of default values:


       This example inserts some rows into table films from a table  tmp_films
       with the same column layout as films:

       INSERT INTO films SELECT * FROM tmp_films WHERE date_prod < '2004-05-07';

       This example inserts into array columns:

       -- Create an empty 3x3 gameboard for noughts-and-crosses
       -- (these commands create the same board)
       INSERT INTO tictactoe (game, board[1:3][1:3])
	   VALUES (1,'{{"","",""},{"","",""},{"","",""}}');
       INSERT INTO tictactoe (game, board)
	   VALUES (2,'{{,,},{,,},{,,}}');

       INSERT  conforms	 to  the SQL standard. The case in which a column name
       list is omitted, but not all the columns are  filled  from  the	VALUES
       clause or query, is disallowed by the standard.

       Possible	 limitations  of  the query clause are documented under SELECT
