PQprepare result

Hi, ALL,

[code]
PGresult *res = PQprepare( m_db, "query1", ... );
PQclear( res );
res = PQprepare( m_db, "query2", ....);
PQclear( res );
[/code]

I presume that it is safe to do the code like this
(re-using the PGresult variable).

Or I have to use its own PGresult for each PQprepare
call?

Thank you.
