configuration parameters *_flush_after were added in 9.6. They are not in
postgresql.conf.sample, but are also not marked GUC_NOT_IN_SAMPLE. Is this
intentional and/or desirable?

Cheers,

Jeff

Hm?

$ grep flush_after src/backend/utils/misc/postgresql.conf.sample
#bgwriter_flush_after = 0 # 0 disables,
#backend_flush_after = 0 # 0 disables, default is 0
#wal_writer_flush_after = 1MB # 0 disables
#checkpoint_flush_after = 0 # 0 disables,

My apologies. I must have gotten my default conf file from the wrong
initdb.
