Обсуждение: Extra indentation in first line

The following documentation comment has been logged on the website:

Description:

Hello,

In some queries there is an extra indentation. For example:

          SELECT to_tsquery('fat') <-> to_tsquery('cat | rat');
             ?column?
-----------------------------------
 'fat' <-> 'cat' | 'fat' <-> 'rat'

But there are no indentation (it's correct) here:

SELECT ts_rewrite('a & b'::tsquery,
                  'SELECT t,s FROM aliases WHERE ''a & b''::tsquery @>
t');
 ts_rewrite
------------
 'b' & 'c'

It seems that there are no such indentations within .sgml files.

If you compare the different branches' versions of that page, it's OK in
"devel", and OK in some very old branches like 9.2, but not OK in any
of 9.3 through 10.  So I'm thinking that somebody broke some
version-specific website markup.  No idea how to investigate further,
but I'm cc'ing the www list for comment.
