DBLINK_BUILD_SQL_INSERT(3)        PostgreSQL 12.3 Documentation        DBLINK_BUILD_SQL_INSERT(3)

       dblink_build_sql_insert - builds an INSERT statement using a local tuple, replacing the
       primary key field values with alternative supplied values

       dblink_build_sql_insert(text relname,
                               int2vector primary_key_attnums,
                               integer num_primary_key_atts,
                               text[] src_pk_att_vals_array,
                               text[] tgt_pk_att_vals_array) returns text

       dblink_build_sql_insert can be useful in doing selective replication of a local table to a
       remote database. It selects a row from the local table based on primary key, and then
       builds a SQL INSERT command that will duplicate that row, but with the primary key values
       replaced by the values in the last argument. (To make an exact copy of the row, just
       specify the same values for the last two arguments.)

           Name of a local relation, for example foo or myschema.mytab. Include double quotes if
           the name is mixed-case or contains special characters, for example "FooBar"; without
           quotes, the string will be folded to lower case.

           Attribute numbers (1-based) of the primary key fields, for example 1 2.

           The number of primary key fields.

           Values of the primary key fields to be used to look up the local tuple. Each field is
           represented in text form. An error is thrown if there is no local row with these
           primary key values.

           Values of the primary key fields to be placed in the resulting INSERT command. Each
           field is represented in text form.

       Returns the requested SQL statement as text.

       As of PostgreSQL 9.0, the attribute numbers in primary_key_attnums are interpreted as
       logical column numbers, corresponding to the column's position in SELECT * FROM relname.
       Previous versions interpreted the numbers as physical column positions. There is a
       difference if any column(s) to the left of the indicated column have been dropped during
       the lifetime of the table.

           SELECT dblink_build_sql_insert('foo', '1 2', 2, '{"1", "a"}', '{"1", "b''a"}');
            INSERT INTO foo(f1,f2,f3) VALUES('1','b''a','1')
           (1 row)
