PSQL: Use a psqlrc File For Common Settings

There are a handful of settings that I inevitably turn on or configure each time I open up a psql session. I can save myself a little time and sanity by configuring these things in a .psqlrc dotfile that is located in my home directory. This will ensure my psql session is configured just how I like it each time I launch it. Here is what my ~/.psqlrc file currently looks like:

\x auto
timing
\pset null 'Ø'
