Dear Postgres specialist,
 
1 Assume you have a table such as the following:
 
CREATE TABLE example( id SERIAL, someData VARCHAR(32) );
 
2 Now, you use a SQL statement to insert the data and get the the id
value back:
 
INSERT INTO example( someData ) VALUES( 'BlaBlaBla' ) RETURNING id; 
 
I wonder if it is possible to retrieve the value of the id field in an
application using the C libpq library. 
 
I pretty much understand how to bind data with the libpq, or how to
retrieve result sets from a SELECT SQL statement, but not how to
retrieve data from that RETURNING clause. (I have many years of practice
of the RETURNING clause in the ORACLE C library, but that is not the
point here).
 
Thank you very much for your help and your patience.
With my best regards.
