They do [1] ;-)

I already answered there.

Yes, con.conn.toggleShowQuery does the trick, again:

#v+
gerhard@gargamel:~$ python
Python 2.2.2 (#1, Nov 30 2002, 23:19:58) 
[GCC 2.95.4 20020320 [FreeBSD]] on freebsd4
Type "help", "copyright", "credits" or "license" for more information.
>>> from pyPgSQL import PgSQL
>>> con = PgSQL.connect()
>>> con.conn.toggleShowQuery
'On'
>>> cursor = con.cursor()
QUERY: BEGIN WORK
>>> cursor.execute("select * from test")
QUERY: DECLARE "PgSQL_0811F1EC" CURSOR FOR select * from test
QUERY: FETCH 1 FROM "PgSQL_0811F1EC"
QUERY: SELECT typname, -1 , typelem FROM pg_type WHERE oid = 23
QUERY: SELECT typname, -1 , typelem FROM pg_type WHERE oid = 1043
>>> result = cursor.fetchmany(5)
QUERY: FETCH 4 FROM "PgSQL_0811F1EC"
>>> result
[[None, 'A'], [None, 'B'], [None, 'C'], [None, 'F'], [None, 'F']]
>>> con.commit()
QUERY: CLOSE PgSQL_0811F1EC
QUERY: COMMIT WORK
>>> 
#v-

This gives me a warning like this:

#v+
WARNING:  PerformPortalClose: portal "pgsql_0811f1ec" not found
#v-

The SQL pyPgSQL emits looks perfectly valid to me. So I'm inclined to think
that the PostgreSQL warning is superfluous, at best.

[1] ... if under psql you use the same SQL that pyPgSQL sends over the wire.
