title: Postgres databases and roles disappeared
body: <p>Yesterday evening I closed my macbook's lid and left work. Came back this morning, turned my computer on, and upon trying to log into psql got a warning that the <em>postgres</em> role didn't exist... Upon further inspection, it seems that all but one of my databases are gone (and the default template0/1, postgres and my user's), as well as every roles but mine (<code>&lt;user&gt;</code>). <code>\du+</code> in the psql console confirms my user has superuser rights. I still tried <code>$ psql -d database_that_disappeared</code>, to no avail. Tried switching to the other postgres versions I have installed locally (9.5.3 --> 9.6.2 --> 9.5.3), with no luck.</p>
  
  <p>I obviously haven't run any brew update or upgrade, nor has OSX automatically updated anything, as I've turned automatic updates off. I have tried both shutting down and rebooting, to no avail either.</p>
  
  <p>Edit: <em>/usr/local/var/postgres/base</em> shows 26 folders + pgsql_tmp, which makes me feel that the <em>data</em> itself isn't gone?</p>
