Is this right? I'm looking at
http://www.postgresql.org/docs/current/static/backup-dump.html
It says, "pg_dump does not block other operations on the database
while it is working. (Exceptions are those operations that need to
operate with an exclusive lock, such as most forms of ALTER TABLE.)"
So pg_dump actually performs an ALTER TABLE sometimes? :S
