But lying in wait is a query that can bring everything crashing to a crawl. I've far too often lived through these experiences and (hate to admit that) at times I have been the cause of the issues. Queries that run for too long are often going to create some cascading effects, most...
To prevent queries on the standby node from being cancelled due to replication conflicts, you can sethot_standby_feedback = on, which will make the standby inform the primary about the oldest transaction running on it. As a result, the primary can avoid cleaning up rows wh...
Long running transactions (involving any table, not just the one being vacuumed) Lagging or stale physical/logical replication slots Abandoned prepared transactions Long running queries on standbys (with hot_standby_feedback = on) Any of these situations can cause your VACUUM to not do any meanin...
man strtol strtoimax, strtol, strtoll, strtoq -- convert a string value to a long, long long, intmax_t or quad_t integer 所以在第13行中我们将一个long int转换为一个int型发生了溢出。 result = strtol(str,NULL,36); 重用内部的DirectFunctionCall 让我们通过再次重用Postgres内部功能来地进行正...

Lastly, you can also track and terminate long running queries on the standby like we discussed for the primary in the long running transactions section above. \n the table (the good news is that manualVACUUMwon’t terminate itself) or ...
Also, they’re always there for me when I need to test out some Postgres statistic fetching queries for our Postgres monitoring tool called pgwatch2. The only annoying thing that could pester you a bit is - if you happen to also run Postgres on the host machine, and want to take a ...
This is fine for long running queries, but in the case of high load and fast queries it might be better to simply ignore results instead of canceling.const query = sql`select pg_sleep 100`.execute() setTimeout(() => query.cancel(), 100) const result = await query...
Aside from the standard features you'd expect from a database GUI tool (creating and managing databases, running queries, editing tables, managing users and permissions, etc.), it also has monitoring tools to monitor the status of database operations. Mac only TablePlus TablePlus first greeted ...
