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). https://gist.github.com/ardentperf/52bd418e44b1be26d7b63af21331cece 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. -Jeremy -- http://about.me/jeremy_schneider
