It looks like that does not work.

[rhaas pgsql]$ PGOPTIONS='-c local_preload_libraries=auto_explain' psql
psql (9.5devel)
Type "help" for help.

rhaas=# select * from pg_background_result(pg_background_launch('show
auto_explain.log_min_duration')) as (x text);
ERROR:  unrecognized configuration parameter "auto_explain.log_min_duration"
CONTEXT:  background worker, pid 31316
