Has anyone experienced a pfree() related core dump in 7.2.3.
Here is my gdb backtrace
0 0x005dbb5c in pfree ()
(gdb) bt

FYI, I'm using the Async Query for my vacuum as shown below and I'm
not doing the PQgetResult(), so I'm hoping that closing the connection will
tear down the backend after finishing the vacuum...
if ( ! PQsendQuery( Conn, SQL.c_str() ) )
{
cout << __FUNCTION__
<< " : Failed to execute Async vacuum ["
<< PQerrorMessage(Conn) << "]\n";
PQfinish(Conn);
return status;
}
PQflush(Conn);
PQfinish(Conn);
