Peter Eisentraut 6ef2448796 Fix a whitespace issue with the man pages
There is what may actually be a mistake in our markup.  The problem is
in a situation like

<para>
 <command>FOO</command> is ...

there is strictly speaking a line break before "FOO".  In the HTML
output, this does not appear to be a problem, but in the man page
output, this shows up, so you get double blank lines at odd places.

So far, we have attempted to work around this with an XSL hack, but
that causes other problems, such as creating run-ins in places like

<acronym>SQL</acronym> <command>COPY</command>

So fix the problem properly by removing the extra whitespace.  I only
fixed the problems that affect the man page output, not all the
places.

<para>
A tablespace parameter to be set or reset. Currently, the only
available parameters are <varname>seq_page_cost</> and
<varname>random_page_cost</>. Setting either value for a particular
tablespace will override the planner's usual estimate of the cost of
reading pages from tables in that tablespace, as established by
the configuration parameters of the same name (see
<xref linkend="guc-seq-page-cost">,
<xref linkend="guc-random-page-cost">). This may be useful if one
tablespace is located on a disk which is faster or slower than the
remainder of the I/O subsystem.
