This has been fixed in PG 9.3 (released today) for the specific options
you supplied:
$ psql -t --pset=footer=off test
Default footer is off.
psql (9.4devel)
Type "help" for help.
CREATE TABLE test (x INT);
CREATE TABLE
SELECT * FROM test;
\x
Expanded display is on.
SELECT * FROM test;
Unfortunately, this did not fix the more simple case where
--pset=footer=off is specified, but not -t:
$ psql --pset=footer=off test
Default footer is off.
psql (9.4devel)
Type "help" for help.
CREATE TABLE test (x INT);
CREATE TABLE
SELECT * FROM test;
x
---
\x
Expanded display is on.
SELECT * FROM test;
--> (No rows)
The attached patch fixes this, and makes it match the rest of the output
formats, which do honor --pset=footer=off alone for footers.
