PostgresQL eating up too much RAM
my Postgresql DB instance averages 3GB of RAM use for like 8 open connections and just a couple of requests a day. It's way too much, i noticed that because of that i've been overpaying for a while alrady.

what constitutes a lot

my biggest table is 1.5 millions
give or take
but size on disk shouldn't impact RAM use ?

i have probably more or less 3 millions rows, but 3GB doesn't feel very reasonable ngl. This should be tweakable in a way ?

arent's indices written in disk too ? if i had 20 GB of data i'd use 20GB of RAM ?
I've had the same instance running on a $5 digital ocean instance without any issue
and the RAM was capped at 2GB
I really believe this is an issue on the side of railway

I see, is there any configuration to cap the PG plugin RAM usage ?

i'm paying a little too much for an app i'm using alone for now
where do i request this ? It is really a serious issue. I'm paying $30 for something that should be $10-15

Just a heads up those limits will be "When we shut off your application"
Not like, throttling your DB for you
Well i actually meant capping RAM usage for plugins and/or app instances for example
especially when so many processes or DBs use as much as they have available
Totally. So lemme find the ticket where we track THAT issue
that would be a great feature
So that you can make sure you're subscribed to the right one
Because it's absolutely something we want to do
Just like, the more upvotes the actual right ticket gets the more we can prioritize it ya know
Sec
of course, i'd like to see that :')
Psych, I lied, they're all under the same ticket
Upvote away please!
dare you

Ya it caches stuff so that your queries can be fast

Candidly, dropping a bill is not a usecase

I could see PG making weird memory optimizations, and the usecase would actually to be to tweak the DB such that you can say “actually, I don’t really care to keep those first queries hot”
For sure
I just wanna be clear about what we should be building here 😄
At 8gb, that’s $80, which does drop your costs by 50% anyways

Oh it’s quite the opposite! It’s saying “Well, I’ve got these resources I might as well use em!”

Wait if it's cheaper than DO why not keep it on Railway for now anyways?
