Wait events are perhaps inspired by oracle's stuff, at least indirectly. It was developed by Robert Haas and Amit Kapila, working for EDB. Traditionally a lot of their customers have migrated from Oracle. The redesigned way of storing stats in memory and pg_stat_io aren't inspired by Oracle. Melanie, who authored pg_stat_io, has never used oracle. I haven't used oracle in ~15 years, and the only thing I remember is fighting crashes in connect_by (I influenced the design of pg_stat_io, and authored large portions of the shared memory stats stuff). Edit: noted Amit's co-authorship of wait events
