PLpgSQL

3 questions:

1. Can I use CREATE SEQUENCE inside a function?
2. I can create this function but I can't get it to run:

CREATE FUNCTION new_proj_pts_seq(int4)
RETURNS text
AS 'DECLARE
proj_ID alias for $1;
seq_name TEXT;
BEGIN
seq_name := ''proj_pts_'' || proj_ID;
create sequence seq_name;
END;
RETURNS seq_name;'
LANGUAGE 'plpgsql';

When I do
SELECT new_proj_pts_seq(9000);
I get:
ERROR: parser: parse error at or near "$1"

The same happens if I assign $1 to proj_ID (instead of aliasing), or
just use $1 in the string concatenation.
I always get the same message.

Considering that all the above is possible/fixable...

3. On the statement 'create sequence seq_name;', will 'seq_name' be
evaluated properly?

Thanks.
