I don't think you can easily find out what connections are open (at least
from the ADO end). In pgAdmin II there is a long running bug that I can't
resolve that prevents dropping a database because I can't persuade *all*
connections to the specified database to close.
It's for this reason that I'd still use option A - option B may be multi
user safe (now that I understand it properly :-) ) but you never know how
ADO is going to handle it. In theory it should only use one connection but
the bug I mention above (knowing the time, effort and experimentation I've
put into fixing it) makes me wonder.
