Josh Kupershmidt 78bae38718 Take an ACCESS SHARE LOCK on the target table, in an initial attempt to prevent concurrent DDL.
This is a first pass at Daniele's suggestion in Issue #8, although it is
definitely still buggy -- it is still possible for another transaction
to get in an AccessExclusive lock and perform DDL either before the
ACCESS SHARE lock is acquired or immediately after it is released.
