TL;DR

Install Postgres 11, and then:

sudo pg_dropcluster 11 main --stop
sudo pg_upgradecluster 9.5 main
sudo pg_dropcluster 9.5 main

How to get an estimate of the impact of writing Postgres logs with log_min_duration_statement = 0:

1. Do select pg_stat_statements_reset(); and wait N seconds (where N >> 60 – say 1-24 hours, covering typical busy hours). Remember when it was, and write down somewhere – this timestamp will be needed!

2. Check if select count(*) from pg_stat_statements is lower than pg_stat_statements.max. If it's equal to it, then raise pg_stat_statements.max and restart with the step 1.

3. Get the estimate:

\set TS_PGSS_RESET 'XXXX-XX-XX XX:XX:XX';

1. pg_dump is a nifty utility designed to output a series of SQL statements that describes the schema and data of your database. You can control what goes into your backup by using additional flags.
   Backup: pg_dump -h localhost -p 5432 -U postgres -d mydb > backup.sql

   Restore: psql -h localhost -p 5432 -U postgres -d mydb < backup.sql

   -h is for host.
   -p is for port.
   -U is for username.
   -d is for database.

The problem

I've frequently been bit by failures restarting my vpn on my Mac. The connection may appear to start up in Shimo (the menu icon will change) but it looks like vpnc can't connect.

Looking at the log, we see the connection gets stuck

ERROR: can't send packet: Can't assign requested address

This has plagued me for a while, and my only fix has been to restart the machine. I hate restarting my machine. So I finally made time to dig in and find a better solution

Deploy without downtime

We deploy without downtime when we can to avoid user frustration. It's pretty rare that we can't.

There's a great talk/slideshow on this, but no convenient reference that we're aware of – hence this document.
