There are lots of examples in the docs, but here's a super simple one in sql:

# create table test (a int);
# create function addone(x int) returns int as $$
# insert into test (a) values ($1); select $1;
$$ language sql;
# select addone(5);
 addone
--------
      5
(1 row)
# select * from test;
 a
---
 5
(1 row)
