<blockquote>
<h1>5.9.2 (April 18, 2026)</h1>
<p>Fix SQL Injection via placeholder confusion with dollar quoted string
literals (GHSA-j88v-2chj-qfwx)</p>
<p>SQL injection can occur when:</p>
<ol>
<li>The non-default simple protocol is used.</li>
<li>A dollar quoted string literal is used in the SQL query.</li>
<li>That query contains text that would be would be interpreted outside
as a placeholder outside of a string literal.</li>
<li>The value of that placeholder is controllable by the attacker.</li>
</ol>
<p>e.g.</p>
<pre lang="go"><code>attackValue := `$tag$; drop table canary; --`
_, err = tx.Exec(ctx, `select $tag$ $1 $tag$, $1`,
pgx.QueryExecModeSimpleProtocol, attackValue)
</code></pre>
<p>This is unlikely to occur outside of a contrived scenario.</p>
<h1>5.9.1 (March 22, 2026)</h1>
<ul>
<li>Fix: batch result format corruption when using cached prepared
statements (reported by Dirkjan Bussink)</li>
</ul>
<h1>5.9.0 (March 21, 2026)</h1>
<p>This release includes a number of new features such as
SCRAM-SHA-256-PLUS support, OAuth authentication support, and
PostgreSQL protocol 3.2 support.</p>
<p>It significantly reduces the amount of network traffic when using
prepared statements (which are used automatically by
default) by avoiding unnecessary Describe Portal messages. This also
reduces local memory usage.</p>
<p>It also includes multiple fixes for potential DoS due to panic or OOM
if connected to a malicious server that sends
deliberately malformed messages.</p>
<ul>
<li>Require Go 1.25+</li>
<li>Add SCRAM-SHA-256-PLUS support (Adam Brightwell)</li>
<li>Add OAuth authentication support for PostgreSQL 18 (David
Schneider)</li>
<li>Add PostgreSQL protocol 3.2 support (Dirkjan Bussink)</li>
<li>Add tsvector type support (Adam Brightwell)</li>
<li>Skip Describe Portal for cached prepared statements reducing network
round trips</li>
<li>Make LoadTypes query easier to support on "postgres-like"
servers (Jelte Fennema-Nio)</li>
<li>Default empty user to current OS user matching libpq behavior
(ShivangSrivastava)</li>
<li>Optimize LRU statement cache with custom linked list and node
pooling (Mathias Bogaert)</li>
<li>Optimize date scanning by replacing regex with manual parsing
(Mathias Bogaert)</li>
<li>Optimize pgio append/set functions with direct byte shifts (Mathias
Bogaert)</li>
<li>Make RowsAffected faster (Abhishek Chanda)</li>
<li>Fix: Pipeline.Close panic when server sends multiple FATAL errors
(Varun Chawla)</li>
<li>Fix: ContextWatcher goroutine leak (Hank Donnay)</li>
<li>Fix: stdlib discard connections with open transactions in
ResetSession (Jeremy Schneider)</li>
