The GUC is marked GUC_NOT_IN_SAMPLE:

+       {"enable_self_join_elimination", PGC_USERSET, QUERY_TUNING_METHOD,
+           gettext_noop("Enable removal of unique self-joins."),
+           NULL,
+           GUC_EXPLAIN | GUC_NOT_IN_SAMPLE
+       },

..which is causing an error in the buildfarm:

# Failed test 'no parameters missing from guc_tables.c'
# at t/003_check_guc.pl line 89.
# got: '1'
# expected: '0'

# Failed test 'no parameters marked as NOT_IN_SAMPLE in postgresql.conf.sample'

# Looks like you failed 2 tests of 3.
