+      The changes made for CVE-2025-1094 had one serious oversight:
+      <function>PQescapeLiteral()</function>
+      and <function>PQescapeIdentifier()</function> failed to honor their
+      string length parameter, instead always reading to the input
+      string's trailing null.  This resulted in including unwanted text in
+      the output, if the caller intended to truncate the string via the
+      length parameter.  With very bad luck it could cause a crash due to
+      reading off the end of memory.
+     </para>
+
+     <para>
+      In addition, modify all these quoting functions so that when invalid
+      encoding is detected, an invalid sequence is substituted for just
+      the first byte of the presumed character, not all of it.  This
+      reduces the risk of problems if a calling application performs
+      additional processing on the quoted string.
