Por que meu pg_basebackup é incompatível com Postgres?

Eu tenho um script de shell de backup que executa o pg_basebackup todas as noites. Quando tento executá-lo, recebo esta mensagem de erro dizendo que pg_basebackup aparentemente não é compatível com Postgres.app versão 16.3.

Eu uso o macOS Sonoma 14.5 (23F79). Este é o meu script de backup:
