title: How can you find a literal percent sign (%) in PostgreSQL using a LIKE query?
body: <p>I have <code>character varying</code> entries in a table where <em>some</em> (not all) values contain percentages, e.g., <code>'12%'</code>, <code>'97%'</code>, etc. I want to find all the values that contain percentages. In other words, I want to find all values that end with a percent sign (<code>'%'</code>).</p>
