the wal_init_zero set to ON cause new WAL files to be filled with zeroes.
It was not crystal clear to me that when wal_recycle is also ON , the
recycled files are not filled with zeroes, because they are not
considered as new. Could we add a sentence stating this?
It currently says:
wal_init_zero: "... causes new WAL files to be filled with zeroes ..."
wal_recycle: "... avoiding the need to create new ones ..."
I'm not sure where exactly to make that more clear.
