bug#22016: 25.0.50; sql-interactive-mode prompts and header alignment in query output

[Phil Sainty]

Regarding the following Question and Answer:

http://emacs.stackexchange.com/q/13315
http://emacs.stackexchange.com/a/18403

In which multi-line SQL queries can result in output like so:

select a, b, c
from table1
where a < 10;

mydb=> mydb=> mydb-> mydb-> mydb->     a     |      b       |   c
----------+--------------+-------
        1 | 2015-01-05   | 59120
        7 | 2015-01-06   | 59121
        3 | 2015-01-07   | 59122
(3 rows)

i.e. we get multiple prompts all on a single line (continuations due
to the multi-line query), and then the header row for the output is
on that same line as well, which means that the column headers don't
line up with their data.

I'm not sure whether this issue is product-specific. Both parties
are using Postgres in this instance.

I've hacked together a workaround for both issues in the above-linked
answer, and that's doing the trick for me, but it would be great if
sql-interaction-mode handled this by default.
