I have reworded the paragraph a bit to be more general so as it would
not need an update once more normalization is applied to utility
queries (I am going to fix the part where we mention that we use the
strings for utilities, which is not the case anymore now):
+  <para>
+   Queries on which normalization can be applied may be observed with constant
+   values in <structname>pg_stat_statements</structname>, especially when there
+   is a high rate of entry deallocations. To reduce the likelihood of this
+   happening, consider increasing <varname>pg_stat_statements.max</varname>.
+   The <structname>pg_stat_statements_info</structname> view, discussed below
+   in <xref linkend="pgstatstatements-pg-stat-statements-info"/>,
+   provides statistics about entry deallocations.
+  </para>

Are you OK with this text?
