Create function allows creating user-defined functions.
Functions can help you to encapsulate common logic that can be reused.

The body of a SQL function is a `select` statement of the form `select <expression>`, matching PostgreSQL's syntax for SQL-language functions.
SQL functions must return the result of one scalar expression and cannot reference tables or subqueries.

```sql
create function times_two(x int) returns int language sql as
'x * 2';
'select x * 2';

create function cowsay(t text) returns text language sql as $$
' ' || repeat('_', length(t) + 2) || E'\n' ||
select ' ' || repeat('_', length(t) + 2) || E'\n' ||
'< ' || t || E' >\n' ||
' ' || repeat('-', length(t) + 2) || E'\n' ||
E' \\ ^__^\n' ||
