pgsql-server: I have noticed that the latex format in psql has some

Log Message:
-----------
I have noticed that the latex format in psql has some bugs:

o "_" is not escaped, and causes TeX to abort, thinking it's a
subscript outside of maths mode. Most of my table and field names
use underscores, so this is a really nasty one.
o The column count is calculated using the contents of opt_align. But
opt_align has one extra element, and so it's always one too many. I
changed it to count the column headings, like all the other output
formats. There may be a bug in computing opt_align that this patch
does not address, but I'm not yet familiar enough with the psql
source to fix this as well.
o The line drawing rules for each border setting (0-3) and expanded
mode didn't always match the documented behaviour and what other
formats (e.g. aligned) did. I made it as conformant as possible,
and also tidied the alignment of the first line of the footer, which
was incorrectly indented.
