Hey,
PostgreSQL 7.3 on i686-pc-linux-gnu, compiled by GCC 2.96

But, I am getting error when I am using the alias key word.
And also when I try to create a C function for the same and excute I am getting the following error
ERROR:  Memory exhausted in AllocSetAlloc(677865842)
And, I am allocating memory using the "palloc"

Dear All,
When I am executing any function with parameter.. I am unable to access them. So, I would be thankful if, anyone can
helpme in teaching this aspect. 

CREATE FUNCTION add_one (integer) RETURNS INTEGER AS '
    BEGIN
        RETURN $1 + 1;
    END;
' LANGUAGE 'plpgsql';
The expected ouput of the above function should be 11 when we pass the 10 to it.... but it returns 1.
Thank you in advance

Hi,

I juste did a copy/paste of your sample on my test DB. I didn't get
any
error message and the function works fine.

I run PostgreSQL 7.3.3

Works fine for me:

regression=# CREATE FUNCTION add_one (integer) RETURNS INTEGER AS '
regression'#     BEGIN
regression'#         RETURN $1 + 1;
regression'#     END;
regression'# ' LANGUAGE 'plpgsql';
CREATE FUNCTION
regression=# select add_one(10);
 add_one
---------
      11
(1 row)

Perhaps you should show us exactly what you did.

            regards, tom lane
