Hello,

About parameter max_wal_size the documentation <https://www.postgresql.org/docs/current/runtime-config-wal.html#GUC-MAX-WAL-SIZE> says: "Maximum size to let the WAL grow to between automatic WAL checkpoints."
Is it correct?

The size between automatic WAL checkpoints or the size of all WAL files in the pg_wal directory?

size between checkpoints, size of all wal's can be higher, see wal_keep_segments.
