Hmm, isn't the confusion over system superuser and postgresql database
superuser excatly the reason this change was suggested? I seem to
recall this is a FAQ (even if it's not in the FAQ). Those who make the
mistake are those who are more familiar with databases than operating
systems. They see 'superuser', and think 'oh, I know what that is' in
specific, not in general. I remember being slightly confused on this
very issue myself the first time I installed pgsql. No other package I can
think of calls it's administrative user the 'foo superuser': in my UNIX
experience, it's like the U.S. President: there's only one individual,
not a class. In fact, the Zope middleware package used to call it's all
powerful user 'superuser', but switched to 'administrator' for this very
reason. Yes, people where typing root passwords into webpages!

As to historical precedent: The account for the person who installs and
manages the database: that'd be the database administrator, DB admin,
or DBA. Surely you've heard of one? I find 'admin' or 'DBA' easy to type
(and in fact, is the term I use when discussing this person) If you use
superuser, there's always a moment of ambiguity, when I must decide from
context (or additional adjectives) if this is the postgresql or system
superuser (dare I say hash collision?)

'Admin' is shorter, has just as long a precedent (or longer) than
superuser, has more of the _right_ connotations in the database community,
and none of the overloading concerning system priviliges that 'superuser'
has.
