Thread: pgsql: Code review for pgstat_get_crashed_backend_activity patch.

Code review for pgstat_get_crashed_backend_activity patch.

Avoid possibly dumping core when pgstat_track_activity_query_size has a
less-than-default value; avoid uselessly searching for the query string
of a successfully-exited backend; don't bother putting out an ERRDETAIL if
we don't have a query to show; some other minor stylistic improvements.
