Just my 2 cents and I generally agree with the sentiment in the comments about Postgres just being rock solid reliable and having great integrations / vendor neutral.
One of the huge benefits I see with Postgres is its extension system. PostGIS is amazing. Can save any company that needs to do heavy geospatial processing $$$ by dodging ESRI. The only database I've found that handles geospatial stuff better is BigQuery, but considering the revolution that was Google Maps over the best decade I don't think that would really surprise anyone.
