opengauss：fail to allocate a zone

一主一备模式下，进行简单测试，一段时间后显示：fail to allocate a zone 通过提供的工具收集日志，结果是死锁导致的： 2022-08-03 14:14:59.865 62ea1252.5025 postgres 139780237289216 PostgreSQL JDBC Driver 1538516 dn_6001_6002 40P01 3377699720531497 [BACKEND] ERROR: deadlock detected 2022-08-03 14:14:59.865 62ea1252.5025 postgres 139780237289216 PostgreSQL JDBC Driver 1538516 dn_6001_6002 40P01 3377699720531497 [BACKEND] DETAIL: Process 139780237289216 waits for ShareLock on transaction 1538556; blocked by process 139780876728064.

OpanGauss中内置函数的插入机制
by 游奕桁 16 Jul '22

16 Jul '22

Hi 近期在开发的过程中需要插入新的内置函数，但是发现opengauss中内置函数的插入机制与postgresql中不同，经过了多种尝试都以失败告终，想请问一下opengauss中的内置函数是通过什么样的机制插入到数据库中的，以及源码中后缀名为.h_for_llt文件是如何发挥作用的，在现有的源码讲解博客中没有发现详细的相关内容。望回复
