​Yes, it is possible. Did you even try?

"test" in that example is called a string. There are bunch of functions
and operators that work with strings. They are documented here:

http://www.postgresql.org/docs/9.4/static/functions-string.html

You'll find the ones that "concatenate" - which basically is a fancy way to
say: "to combine" or "to join together" - to be quite useful when faced
with problems of this sort.
