On Insert: column reference "score" is ambiguous
<p>I have the following command in postgresql:</p>

<pre><code>INSERT INTO word_relations(word1_id, word2_id, score) VALUES($1, $2, $3)
ON CONFLICT (word1_id, word2_id) DO UPDATE SET score = score + $3`)
</code></pre>

<p>I get the following error:</p>

<pre><code>column reference "score" is ambiguous
</code></pre>

<p>I thought it was odd as I am only using one table. Any ideas?</p>
