AWS PostgreSQL max_connection per instance type
The default formula use by AWS RDS to calculate the max_connections parameter is: LEAST({DBInstanceClassMemory/9531392},5000)
But It's hard to find the exact value of DBInstanceClassMemory.
So, here are the values I got when I ran the SQL commmand: show max_connections; in some RDS instances:
| Instance type | RAM (GB) | max_connections |
|---|---|---|
| db.t2.small | 2 | 198 |
| db.t2.medium | 4 | 413 |

| diskutil list | |
| # This will output a bunch of info about all of the disk drives connected to | |
| # your Mac. Each entry will have a header in the form "/dev/diskX", where X is | |
| # some number starting at 0. Now, insert your USB drive and run the command | |
| # again. You should see a new entry. Make note of the name (ie, /dev/diskX). | |
