Here's my psqlrc file which has pretty solid logic for detecting between
Community PostgreSQL, RDS PostgreSQL and Aurora PostgreSQL. Note that
it just assumes "community/oss" as a default if it doesn't detect the
other two. Should be easy enough to add detection of other hosted
environments into the query with the "priority" column (as long as
there's a reliable way to detect).

This psqlrc also detects read-write versus read-only (e.g. hot standby),
and the usual username/database/superuser info and builds everything
into the prompt in a way that suits me.
