Improve MariaDB's connection

[louislam]

Knex sometimes throws Error: read ECONNRESET. Trying to improve this.

knex/knex#3447 (comment)

Actually, I don't know how to solve this issue. Setting the pool doesn't seem to be working.

The issue only happens when the database connection is idle for too long.

Setting propagateCreateError to false is a option, but the drawback is all db errors will be muted.

We could just create a no-op which is executed once every minute in a setInterval to keep the DB active, or am I missing something?

This issue should only happen for users who have not set up any monitors, right?

It can also affect MariaDB with custom timeout settings, also a very long interval monitor.

I just re-read the knex/knex#3447 (comment). It looks like I can override the validate function to prevent this.

I added it wrongly, that might be the reason why min: 0 was not working. Will test it again.
