If you concerned about SELinux support may not drive explosive growth
in the number of PostgreSQL users, it is correct. It focuses on the
people who concerned about system security including RDBMS.
It is indeed a niche. All the people does not store their classified
information within databases. But, it is also a fact there are certain
demands, not limited to existing SELinux and PostgreSQL users.
("Synergetic effect" is a correct English expression?)

Now PostgreSQL has various kind of optional features. I think these are
not always valuable for all the people, but it is valuable for users who
enabled the features. SELinux support is not a special case.
