I will be attending the 11th annual PGCon 2017 http://www.pgcon.org/2017 on May 23-27, 2017. This is a great place to meet the active developers of PostgreSQL http://www.postgresql.org/ as they meet on May 24, 2017 for the Developers Unconference. In addition to the Unconference, there are tutorials on May 23rd & 24th with the main conference on May 25th & 26th. Many times there are also activities on the Saturday after the conference, May 27th. Last year there was a Users Unconference held on that day.
I currently have @ChelnikTravels and will be bringing him with me for the auction @PGCon.
