- 主数据库节点远程读取备数据库节点数据页辅助函数

gs_read_block_from_remote用于读取非段页式表文件的页面。默认只有初始化用户可以查看，其余用户需要赋权后才可以使用。

pg_read_binary_file_blocks用于读取数据，非压缩表返回实际数据，压缩表返回压缩后的数据。默认只有初始化用户可以查看，其余用户需要赋权后才可以使用。

gs_read_segment_block_from_remote用于读取段页式表文件的页面。默认只有初始化用户可以查看，其余用户需要赋权后才可以使用。 - 主数据库节点远程读取备数据库节点数据文件辅助函数

gs_read_file_from_remote用于读取指定的文件。gs_repair_file利用gs_read_file_size_from_remote函数获取文件大小后，依赖这个函数将远端文件逐段读取。默认只有初始化用户可以查看，其余用户需要赋权后才可以使用。

gs_read_file_size_from_remote用于读取指定文件的大小。用于读取指定文件的大小，gs_repair_file函数修复文件时，要先获取远端关于这个文件的大小，用于校验本地文件缺失的文件信息，然后将缺失的文件逐个修复。默认只有初始化用户可以查看，其余用户需要赋权后才可以使用。 - 账本数据库函数
