#!/usr/bin/env bash
# SecAFS CLI 端到端验证：使用 PostgreSQL 运行 init、fs ls、mount 等命令
# 用法: ./scripts/e2e-cli-postgres.sh [POSTGRES_URL]
# 示例: ./scripts/e2e-cli-postgres.sh postgres://secafs:secafs@localhost:5432/test
#
# 要求：在可访问 PostgreSQL 的环境下运行（本机或已端口转发的远程库）。
# SDK 默认带 connect_timeout=10，连接失败会在约 10 秒内报错。
