Thats OK, but my question is why did the original insert not take place.
Syntax error was in the select query that is fired as a result of the trigger

Thanks,

    Because there's a syntax error.

    test=# INSERT INTO headers (id, header_content) VALUES (1, SELECT raw_email FROM parser WHERE id = 1);
    ERROR:  syntax error at or near "SELECT" at character 53
    LINE 1: ...SERT INTO headers (id, header_content) VALUES (1, SELECT raw...
                                                                 ^
    test=# INSERT INTO headers (id, header_content) VALUES (1, (SELECT raw_email FROM parser WHERE id = 1));
    ERROR:  relation "headers" does not exist
    test=#

    Perhaps you should verify the syntax of your queries in a less
    demanding environment, like psql, first.
