title: How do I reload Postgres.app config without restarting?
body: <p>With a regular postgres install, I would do this either by sending SIGHUP to the postgres process, or by running <code>pg_ctl reload</code>. With Postgres.app, however, I'm unsure about where to send SIGHUP (to the Postgres.app process, or one of the workers?), and attempting to run <code>pg_ctl reload</code> (after tracking it down to <code>/Applications/Postgres.app/Contents/Versions/9.3/bin</code> yields only complaints about PG_DATA being unset.</p>
  
  <p>So, how do I reload the configuration files for Postgres.app without restarting the whole server? Is this possible?</p>
