Depends on what you mean by "failed". Do you mean an error was
raised? Then you'll just get a normal error message. To catch this,
check the error trapping section of the PL/pgSQL documentation.
Do you mean nothing was inserted? If so, you won't catch this in your
above code. You can check the FOUND special variable after the INSERT
to see if anything was inserted and set your result message based on
that.

No. BEGIN/END blocks in PL/pgSQL are not equivalent to SQL BEGIN/
COMMIT transactions.
