AWS maintains a nice table of both the Community End of Life and RDS End of Standard Support dates for major versions of PostgreSQL. I had trouble finding this info all in a single place elsewhere.
PostgreSQL has an official page documenting their versioning policy and when the first and last release dates of each major version were. This doesn't include community end of life dates though.
