node.js - node.js module support for postgres large objects (lo not bytea)

Question

It seems that "npm pg" (https://github.com/brianc/node-postgres) is the prefered module to interact with a postgres database from a node.js script.

nevertheless this module does not support binary large objects in the form of postgres "Large Objects". It only support the bytea format.

Is there a module that I am missing that has lo support ?

您可能必须编写自己的支持。请注意，libpq 基本上只是通过 SQL 接口调用函数。有关更多文档，请参阅http://www.postgresql.org/docs/9.1/static/lo-funcs.html。

如果需要，您可以参考 libpq 客户端接口文档，然后使用\df以查看如何在 PostgreSQL 中调用这些文档。
