Good editorial.    I hate over-specialisation, so it's really good to see someone advocating adequacy over a range of DBA functions instead of exceptional ability in just one of those functions.   I'm a died-in-the wool generalist myself, and while being the DBA (managing our in house databases plus those on our servers on our customers' sites scattered round the world) was part of my my last job it was not a large part, and  and I've often wondered why so many DBAs specialise as "production dbas" and dont understand schema design or normalisation, or as "development DBAs" and can't specify a decent backup and recovery system including proper validtion of backups.  I guess I was an adequate DBA - I certainly never had time to be an exceptional one given my other responsibilities.
