<p>
Two new Berkeley DB SQL API specific pragmas have been
added, <code class="literal">bdbsql_shared_resources</code> and
<code class="literal">bdbsql_set_lock_tablesize</code>.
<code class="literal">bdbsql_shared_resources</code> is used to set
the maximum amount of memory, in bytes, to be used by shared
structures in the main environment region, which is useful in
applications with a large number of tables, transactions, or
threads. <code class="literal">bdbsql_set_lock_tablesize</code> is used
to set the number of buckets in the lock object hash table in
the Berkeley DB environment, which is useful if an application
has many concurrent long running transactions.
