postgreSQL function call packet
<p>As postgreSQL documentation says about it's packets <a href="https://www.postgresql.org/docs/8.2/static/protocol-message-formats.html" rel="nofollow">here</a> a function call must send a packet with <code>'F'</code> identifier to server.</p>

<p>So I defined a simple function and called it with <code>select</code> statement and after monitoring my connection port using <a href="https://www.wireshark.org/about.html" rel="nofollow">wireshark</a> I see no <code>'F'</code> identified packet, just multiple simple query packets (<code>'Q'</code> identified).</p>

<p>Am I missing something here?</p>
