Pushed the patch. Thanks!

Using the newly introduced mechanism, we can now easily extend
the log_lock_failure GUC to support additional NOWAIT lock failures,
such as LOCK TABLE ... NOWAIT, ALTER TABLE ... NOWAIT,
ALTER MATERIALIZED VIEW ... NOWAIT, and ALTER INDEX ... NOWAIT.

I've attached a patch implementing this.
