[ADMIN] record locking

[Delain Huggins]

We are getting ready to set up a Postgres database w/Access frontend with 
15-25 users.  What are the record locking concerns that we need to be aware 
of?  Where is record locking set and what levels are there if any?  Can 
queries/reports be run off a record that is being edited at the same time? 
We haven't been able to find much info on Postgres and record locking.

Thanks
