If you get the below relation error it probably means you have spelled the table name wrong in a select statement. I was going through multiple tables tonight in a PostgreSQL database attempting to check a certain ID on a per table basis and I came across a table that provided the below error.
I recently installed the Youtube With Fancy Zoom WordPress plugin on one of my personal web sites so I could upload and display videos of my daughters. This plugin allows you to upload videos to the YouTube, reference them in your WordPress admin, and then display them in a nice pop up window on your website. This way they are streamed from YouTube but the person visiting your site doesn’t have to leave your site to view the video.
