更多信息(来自我自己的研究结果从Oracle迁移 - > Postgres)
序列 - 是
包裹 - 否(PG中不存在概念)
功能 - 是,程序 - 否(也没有INOUT或OUT参数)
全文 - 是,tSearch2
触发器 - 是
工作 - 否,(但是计划的任务可以通过其他方式实现)
同义词 - NO(可以使用search_paths和模式进行处理)
复制 - 根据需要不止一个选项
你会错过某些Oracle功能,但是一旦你进入了postgres的
,你就不会回头了。还要考虑你需要多少钱才能节省许可费!

它只是我,还是有一阵我正在考虑postgres
来自oracle背景最近的问题?在过去一个月左右的时间里,是否有一些用db / rag写的postgres吗?

Bit more info (from my own findings migrating from Oracle -> Postgres)
Sequences - YES
Packages - NO (concept doesn''t exist in PG)
Functions - YES, Procedures - NO (also no INOUT or OUT parameters)
Full-text - YES, tSearch2
Triggers - YES
Jobs - NO, (but scheduled tasks can be implemented in other ways)
Synonyms - NO (can be frigged using search_paths and schemas)
Replication - more than one option depending on requirement
You will miss certain Oracle features, but once you get into the swing
of postgres you''ll not look back. Also consider how much money you''ll
save in license fees!

Is it just me, or has there been a rash of "I''m thinking about postgres
and coming from an oracle background" questions recently? Was there some
writeup of postgres in a db rag in the last month or so?
