Join Grant Fritchey and Ryan Booz in this on-demand webinar as they uncover the secrets behind stored procedures and functions between the two database platforms and share how to most effectively use them. Webinar PostgreSQL PostgreSQL 101: Data Types While there are common data types used...

“Connection management is the best argument for MySQL. Nevertheless, there is actually no real reason not to use PostgreSQL in any relational use case. This is especially true if you consider the developments in the last 3 years. Postgresql is years ahead of any competitor when it comes to ...
Krosing, its original designer.As usual for a book of this type, things start off with relative simplicity. The authors make a very important note I try to convey to staff developers regularly: let the database do its job. The database is there to juggle data, handle set theory, and ...
在使用数据库前,是启动数据库,启动数据库前是initdb(初始化数据库);一起来看一下initdb做了什么吧。初始化数据库的操作为: ./initdb -D /usr/local/pgsql/datainitdb把用户指定的选项转换成对应的参数,通过外部程序调用的方式执行postgres程序。pos
So I can't really make the best judgment of the practicality of each approach. Edit: We should also think about the best course of action for backporting. Can we do this in one go to release-24.11 or do we need to go through staging there as well?wolfgangwalther marked this pull requ...
