Plpgsql function syntax error at first coalesce statement

Hi all,

I'm trying to write my first plpgsql function and I'm running into a
problem that may or may not have to do with a coalesce statement.

I wrote a very similar sql function that does basically the same thing
for just one trainer where I pass in an id number and that one works fine.

I re-used  much of the code from that one to write this plpgsql function
that is supposed to retrieve all trainers. I'm using the example in 38.6.4

http://www.postgresql.org/docs/8.4/interactive/plpgsql-implementation.html#PLPGSQL-RECORDS-ITERATING

as my basic template.

CREATE or replace FUNCTION view_all_trainers()

I'm sure this is something simple but I've been staring at it so long
now I can't see the forest for the trees.
