I'm guessing they were probably created in 9.2.

I guess someone installed pgreorg, ran its scripts to install its functions
into the DB, and then removed pgreorg without removing its scripts.

See Sergei's response:

You probably want to install this package for the new version (9.6 or 10 or
11).

[pryzbyj(at)TS-DB ~]$ rpm -ql postgresql11-contrib |grep -E '(uuid-ossp|adminpack|hstore)\.control'
/usr/pgsql-11/share/extension/adminpack.control
/usr/pgsql-11/share/extension/hstore.control
/usr/pgsql-11/share/extension/uuid-ossp.control
