Accessing an array element from a function

[Mike Nolan]

This may be mostly a documention issue:

I have a function with two parameters that returns an array: text[].

I want to access just the first element of that array within
my SQL statement.

This doesn't work:

select myfunc(1,2)[1];

This does work:
select (myfunc(1,2)[1];

If that's how it's supposed to work, is that documented somewhere?

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to ma*******@postgresql.org)

I suppose you meant

select (myfunc(1,2))[1];
