问题 I am quite new in Arch and a total beginner in PostgreSQL, so this may be a very basic question. I installed postgresql 11.5-4 from extra and pgadmin 4 from AUR, both seem to be running well. I created a test DB with the following command: initdb -D /home/lg/test-db I got the answer: You can start the db-server using: pg_ctl -D /home/lg/test-db -l logdatei start I tried that and got: pg_ctl -D /home/lg/test-db -l logdatei start waiting for serer to start.... stopped pg_ctl: could not start

由 空扰寡人 提交于 2021-02-10 08:56:13
摘要： 2018年云数据库RDS发展上，不但针对MySQL、SQL Server、PostgreSQL提供了适合个人入门用户的基础版产品，以实惠的价格普惠广大中小用户。更加入最新的MariaDB TX企业版，及大幅度提高PPAS的Oracle兼容性，从企业需求出发，重点在全生命周期、全链路安全、全链路监控、全方位运维、多引擎覆盖 5个方面进行发力，为企业用户提供更优质的云数据库服务。 云计算已经进入普及期，不少企业开始从自建数据中心转向云计算。在云计算资源的使用上，从最开始只是使用IaaS层基础资源，转向使用包括云数据库在内的各类PaaS资源。数据库是企业IT架构的核心部分，RDS关系型数据库服务已经成为企业重度依赖的云服务。 过去7年的持续发展，2018年阿里云首次进入Gartner的数据库魔力象限，能够入选Gartner，这是中国数据库厂商的一次突破。阿里云入围Gartner充分说明，在新一波技术浪潮之上进行创新，才可能做出突破。云数据库已经不仅仅是简单地完成数据库在云资源中的搭建，数据库曾经是IT系统中最昂贵的投入之一。对企业CXO们（CEO、CFO、CTO、CIO等）而言，更加灵活的生命周期管理，可以实现成本的合理投入及灵活管理。对DBA技术人员而言，更高的安全性、更全面的监控能力、更便捷的运维方式，将改变DBA在企业的工作模式及地位。 从企业管理者及DBA的角度

fixed width data into postgres

由 ⅰ亾dé卋堺 提交于 2021-02-10 08:33:48
问题 Looking for good way to load FIXED-Width data into postgres tables. I do this is sas and python not postgres. I guess there is not a native method. The files are a few GB. The one way I have seen does not work on my file for some reason (possibly memory issues). There you load as one large column and then parse into tables. I can use psycopy2 but because of memory issues would rather not. Any ideas or tools that work. Does pgloader work well or are there native methods? http://www

In Postgresql how to order by date while keeping custom date format

由 给你一囗甜甜゛ 提交于 2021-02-10 08:17:06
问题 The issue is that using to_char will turn order by date into order by ascii. Example: SELECT foo, bar FROM baz ORDER BY foo; I would like to format foo using to_char, but doing this will affect the order: SELECT to_char(foo,'dd/MM/yyyy') as foo, bar FROM baz ORDER BY foo; Because foo now is of type text. There is a way to correctly do this? Or only in the code? 回答1: You can use a different alias for the formatted column: SELECT to_char(foo,'dd/MM/yyyy') as formatted_foo, bar FROM baz ORDER BY
