1、修改配置文件,../data/postgresql.conf,将参数重新配置:max_locks_per_transaction = 1024,然后重启数据库即可 2、减少过程中操作表的数量,即将一个大的存储过程拆分成若干小过程,再进行执行,最终我们采用的是这个方法,因为根据官方的描述,默认配置是经过验证最合理的配置,将配置调大可能会产生未知的风险 ———...

大部分的消耗maintenance_work_mem 内存的情况大多是发生在vacuum 上的,所以定期的去监控一下dead tuples 和 表的膨胀率对发现vacuum 内存的消耗也是有一定帮助的。 Postgresql 的内存使用中如果出现OUT OF Memory 的可能, 1 定位错误日志,发现错误日志中的关于out of memory 的错误信息 2 根据错误信息,发现时由于...

Postgresql 的内存使用中如果出现OUT OF Memory 的可能, 1 定位错误日志,发现错误日志中的关于out of memory 的错误信息 2 根据错误信息,发现时由于 wrok_mem 有关的问题 (如查询无法分配内存) 或者是 vacuum 或者 其他消耗 maintenance_work_mem 导致内存不足产生的问题 ...
I noticed that in Postgresql it is 30 seconds faster, but I guess with 200Million rows, because of constant rate, TDB should be faster. But when I simply want to make a SELECT COUNT(*) FROM test_table_3, I got this error: ... WARNING: out of shared memory WARNING: out of shared...
We increased this number but still we get a out of shared memory (max_pred_locks_per_transaction = 192). Everytime we start the script again it runs for some time then gives this error message. On Postgres 8.1 we did not have this problem. Here is a piece of t...
