Re: BUG #18821: Need delete files in pg_wal, size is bigger overcome limit max_wal_size

Use this command to eliminate files of pg_wal, but when execute this
command, it doesn´t have desired result

sudo -u postgres /usr/pgsql-15/bin/pg_archivecleanup -d
/var/lib/pgsql/15/data/pg_wal/ $(sudo -u postgres psql -Atc "SELECT
pg_walfile_name(pg_current_wal_lsn());")

Additionally execute the command CHECKPOINT to force of elimination of old
