Description:

psql does not relate to footer settings in extended mode
Sometimes we need to run a sql command withot generating header and footer.
This can be done using the -t flag and --pset=footer=off
The problem is that the footer is still diaplyed even if it was set to off
if we use the extended mode for the query (-x flag)

Steps to Reproduce:
1) create a table without any data
for example
create table text(i int);
2) run
psql -U <user> -t --pset=footer=off <db>
3) No output is generated
4) run
psql -U <user> -t --pset=footer=off -x <db>
5) Output generated : "(No Rows)"

Actual results:
psql does not honour the footer settings when output is defined to be in
Extended Mode

Expected results:
psql should not generate any output is query has no results and -t and
--pset=footer=off were given
