Hello
a := exprx
is internally translated :
get result of SELECT exprx
and store it to a
so you can write select sin(10); then you can a := sin(10)
but you can too use subselect like:
SELECT (SELECT v FROM foo LIMIT 1) ~ you can write
a := (SELECT v FROM foo LIMIT 1);
that is equal to S

You found assignment :). Sure, you can use it.

I noticed that in pl/pgsql simply
result := funcname(func,args,...);
just works.
Should i rely on it or take it as a coincidence? :)
