<li> Improvements to the [.recover dot-command] in the [CLI] so that
     it recovers more content from corrupt database files.
<li> Enhance the [RBU] extension to support [indexes on expressions].
<li> Change the schema parser so that it will error out if any of
     the type, name, and tbl_name columns of the [sqlite_master table]
     have been corrupted and the database connection is not in
     [writable_schema] mode.
<li> The [PRAGMA function_list], [PRAGMA module_list], and
     [PRAGMA pragma_list] commands are now
     enabled in all builds by default.  Disable them using
     [-DSQLITE_OMIT_INTROSPECTION_PRAGMAS].
<li> Add the [SQLITE_DBCONFIG_ENABLE_VIEW] option for [sqlite3_db_config()].
<li> Added the [TCL Interface] [config method] in order to be able to
     disable [SQLITE_DBCONFIG_ENABLE_VIEW] as well as control other
     [sqlite3_db_config()] options from TCL.
<li> Added the [SQLITE_DIRECTONLY] flag for
     [application-defined SQL functions] to prevent those functions from
     being used inside triggers and views.
<li> The legacy [SQLITE_ENABLE_STAT3] compile-time option is now a no-op.

<p>The "complete" method is useful when building interactive applications
in order to know when the user has finished entering a line of SQL code.
This is really just an interface to the 
<a href="c3ref/complete.html"><b>sqlite3_complete()</b></a> C
function.

METHOD config {

<p>
The "config" method queries or changes certain configuration settings for
the database connection using the [sqlite3_db_config()] interface.
Run this method with no arguments to get a TCL list of available
configuration settings and their current values:

<blockquote>
<i>dbcmd</i>&nbsp;&nbsp;<b>config</b>
</blockquote>

<p>The above will return something like this:

<blockquote>
enable_fkey 0 enable_trigger 1 enable_view 1 fts3_tokenizer 0 load_extension 0 no_ckpt_on_close 0 enable_qpsg 0 trigger_eqp 0 reset_database 0 defensive 0 writable_schema 0 legacy_alter_table 0 dqs_dml 1 dqs_ddl 1
</blockquote>

<p>Add the name of an individual configuration setting to query the current
value of that setting.  Optionally add a boolean value to change a setting.
For example, turn off support for the [double-quoted string literal]
misfeature like this:

<blockquote><pre>
db config dqs_dml 0
db config dqs_ddl 0
</pre></blockquote>
}

METHOD copy {

<p>
The "copy" method copies data from a file into a table.
It returns the number of rows processed successfully from the file.
