Hi:

11.3 on linux

I've come up with a plan to archive data from my main DB which involves creating other DBs on the same server.  But even though there will be zero activity on the archive DBs in terms of insert/update/delete, and almost no activity in terms of select, I'm still worried that the mere existence of these other DBs will steal resources away from the instance and degrade performance in my main DB.

*Why?*  If the data is just sitting there like a dead lump, it's not using any RAM or CPU cycles... And if you're afraid of autovacuum and autoanalyze stealing resources, then disable them (at the table level).
