Text editors are an essential tool for every developer, and there is no right answer on which to use. It depends quite a bit on how you learned, and how your mind works. I grew up on the command line before every touching a GUI, and that has stuck with me throughout the years. This is reflected in my choice of text editors: Sublime Text 3 when in a GUI environment, and emacs for the terminal.
We were lucky enough to host PGConf Philly 2018, the third year we've hosted the conference for PostgreSQL at The Wharton School. The event brought PostgreSQL enthusiasts from the east coast together for an afternoon of learning, sharing, and fun. Jim Mlodgenski started the event showing some trends in PostgreSQL growth; Philadelphia is the third largest local PG group, behind only New York and San Francisco. Yes, we're bigger than Chicago, Seattle, and Austin!
