使用已编译PostgreSQL二进制包编译mysql_fdw

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 上周写的帖子： 为PostgreSQL编译Windows下的mysql_fdw 还是有人不会，所以再写一篇用二进制包编译。 1、下载 PostgreSQL 二进制包： Download PostgreSQL Binaries ，点击 下载。 这是EnterpriseDB公司下载地址，不用担心我编译的版本有木马。 （真有人不放心，出门在外有戒心不是坏事，不用就是，EDB的总能放心用吧。） 文件名是postgresql-11.4-2-windows-x64-binaries.zip，包看起来很大是因为包含pgAdmin4以及Python环境。 解压之后我把它们放在目录：C:\postgresql-11.4-2-bin 不是好习惯，主要是为了省事，而且我的虚拟机只有一个C盘。 2、克隆 mysql_fdw 源代码 这个不需要再细说，假设放在 C:\mysql_fdw 目录。 3、安装 MySQL 开发用客户端 跟以前操作一样，假设放在 C:\MySQL\6.1 目录。 4、下载 mysql_fdw.sln、mysql_fdw.vcxproj、MYSQL_FDW.def 这三个文件放到 C:\mysql_fdw 下。 如果是不熟悉VC++，建议跟上边使用相同的目录名，不用修改。 用 百度云盘 分享，过段时间可能会失效

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . What would be the step by step walk-through for building a basic Entity-Relationship Diagram from pgAdmin? Would there be some plugins for doing that in pgAdmin?

PostgreSQL - How to see Function Text/Source in pgAdmin?

由 元气小坏坏 提交于 2019-12-12 10:59:17
问题 I want to be able to SELECT the code of a Function. When I try this Query: select prosrc from pg_proc where proname = 'my_proc' I get an empty column. The thing is, it seems column prosrc does hold the function text. When I try this Query: select proname from pg_proc where prosrc ~* 'part of Function text' I get the correct number and names of Functions. It just doesn't display prosrc. Any idea?
