pgsql: Fix indentation of verbatim block elements Block elements with

Log Message:
-----------
Fix indentation of verbatim block elements

Block elements with verbatim formatting (literallayout, programlisting,
screen, synopsis) should be aligned at column 0 independent of the surrounding
SGML, because whitespace is significant, and indenting them creates erratic
whitespace in the output. The CSS stylesheets already take care of indenting
the output.

Assorted markup improvements to go along with it.
