https://www.postgresql.org/docs/current/continuous-archiving.html#BACKUP-ARCHIVING-WAL

"It is important that the archive command return zero exit status if and 
only if it succeeds. Upon getting a zero result, PostgreSQL will assume 
that the file has been successfully archived, and will remove or recycle 
it. However, a nonzero status tells PostgreSQL that the file was not 
archived; it will try again periodically until it succeeds."
