Yeah, perhaps. The term "bootstrap superuser" is reasonably well
established by now --- I count half a dozen uses in our SGML docs
and another dozen or so in the code --- and it's certainly more
specific than "database superuser". We should probably create
a glossary entry for it and then change all the uses of "database
superuser" as appropriate.

However ... it looks to me like some of those uses just mean to
distinguish between Postgres-specific superuser-dom as opposed
to whatever the term might mean out in the operating system.
But I'm not sure that anybody really uses that term for an OS-level
concept on any popular OS, so it feels a bit pedantic as well
as confusing. Should we leave those usages alone, or reduce them
to just "superuser"?
