attn.: psycopg users -- simple question - Mailing list pgsql-general

Sorry to burden this list (again) with a psycopg question.
I'm stuck at a table creation step and am not getting results
from their list.

Question:  what's the appropriate syntax for specifying a primary
key?

My very simple table creation test (based on their "first.py"
example is failing ...  Here's what I'm trying.  Non-pythonated
syntax works in pgsql:

no go in psycopg:
    curs.execute("""CREATE TABLE key_test (
    key_col CHAR(9) PRIMARY KEY,
    nother_col CHAR(256))""")

pure joy in pgsql:
    cs_test=# CREATE TABLE key_test (
    cs_test(# key_col CHAR(9) PRIMARY KEY,
    cs_test(# nother_col CHAR(256)
    cs_test(# );

Thanks again!
