Peter Eisentraut bb4eefe7bf doc: Improve DocBook XML validity
DocBook XML is superficially compatible with DocBook SGML but has a
slightly stricter DTD that we have been violating in a few cases.
Although XSLT doesn't care whether the document is valid, the style
sheets don't necessarily process invalid documents correctly, so we need
to work toward fixing this.

This first commit moves the indexterms in refentry elements to an
allowed position.  It has no impact on the output.

Use <xref linkend="SQL-ROLLBACK"> to

<para>
Issuing <command>COMMIT</> when not inside a transaction does
no harm, but it will provoke a warning message.

To commit the current transaction and make all changes permanent:

<title>Compatibility</title>
<para>
The SQL standard only specifies the two forms
<literal>COMMIT</literal> and <literal>COMMIT
WORK</literal>. Otherwise, this command is fully conforming.
