Creating Tables in Functions

All,

I am trying to create a function that will create a temporary table and fill
that table with data. Here is my function definition below (much simplified
for this discussion):

create function my_function() returns int4 as'

create temp table my_table(a integer);
insert into my_table values (1);
' language 'sql';

When I try to create this function, I always get the error:

ERROR: Relation 'my_table' does not exist

Of course if doesn't exist, I haven't created it yet! What am I doing
wrong? I am using 7.0. Thanks in advance for any help.
