I see.

You cannot catch an exception in SQL, as far as I know (unless you use a DO
statement, which was introduced in PostgreSQL 9.0).

You could use a "poor man's DO" by creating a function that does
what you want, catch the exception in PL/pgSQL, call the function and drop it.

But I really think that this should be handled on the application side,
i.e. your code should ignore the exception.
