Re: libpq-fe: PQgetvalue() ?

AFAIK it does allocate memory.
You cannot PQclear(pgresult_varible) while cstring_varible is in use.
You do not need to free cstring_variable, PQclear(pgresult_varible) will do.
I personally prefer to allocate local memory, "strcpy" PQgetvalue,
and then PQclear. But that's a matter of taste, I suppose.
