OK thanks for the advice. <br /><br />What I'm trying to overcome is where we've got a long report running and the
processthat is taking data from the main database cannot complete because of the drop table. I believe a DELETE (and
possiblyTRUNCATE?) doesn't need an exclusive lock on the table and therefore can continue.<br /><br />I've introduced a
--delete-not-dropoption which simply does a DELETE FROM % rather than 'DROP and then CREATE'. <br /><br />I hope this
soundssensible and I haven't missed something - I'm still learning!<br /><br />Rob<br /><br /><br /><div

shouldpost *before* you have a patch you're happy with. As<br /> soon as you have a specific plan of what you want to
doit's best to post an<br /> outline of it. That way you at least have a chance of avoiding wasting work in<br /> the
wrongdirection.<br /><br /> Sometimes things don't really work out that way -- sometimes the plan sounds<br /> good and
itonly becomes apparent there's a better way later -- but you're<br /> best off getting the best chance you can.<br
/><br/> Incidentally, I don't know exactly what the use case you're trying to cover<br /> here is but you should
considerlooking at TRUNCATE instead of DELETE if<br /> you're really deleting all the records in the table and can
acceptlocking the<br /> table.<br /><font color="#888888"><br /> --<br /> Gregory Stark<br /> EnterpriseDB
