Zero padding in replication origin's checkpointed on disk-state.
This seems to be largely cosmetic, avoiding valgrind bleats and thelike. The uninitialized padding influences the CRC of the on-diskentry, but because it's also used when verifying the CRC, that doesn'tcause spurious failures. Backpatch nonetheless.It's a bit unfortunate that contrib/test_decoding/sql/replorigin.sqldoesn't exercise the checkpoint path, but checkpoints are fairlyexpensive on weaker machines, and we'd have to stop/start for that tobe meaningful.Author: Andres FreundDiscussion:https://postgr.es/m/20170422183123.w2jgiuxtts7qrqaq@alap3.anarazel.deBackpatch: 9.5, where replication origins were introduced
