I would like to apply the following patch to the CVS tree. It allows
pgmonitor to show query strings even if the backend is not compiled with
debug symbols.
It does this by creating a global variable 'debug_query_string' and
assigning it when the query begins and clearing it when the query ends.
It needs to be a global symbol so gdb can find it without debug symbols.
Seems like a very safe patch, and it allows pgmonitor to be much more
useful until we get a shared memory solution in 7.2.
Is this OK with everyone?
