If something doesn't work then it's helpful to describe what you
expect to happen and what actually does happen. In this case you
were probably expecting the value 1 to be returned, but you got
the following error instead:
ERROR: syntax error at or near "1"
CONTEXT: compile of PL/pgSQL function "test1" near line 1
The function doesn't follow the correct PL/pgSQL structure. See
the PL/pgSQL documentation, especially the "Structure of PL/pgSQL"
section:
http://www.postgresql.org/docs/7.4/static/plpgsql.html

That's the correct syntax for an SQL (LANGUAGE sql) function but
not for PL/pgSQL.
