Generic terminal-based data browsing & entry

I'm looking for a simple application which supports table-based and
card-based browsing and runs on a character terminal. Field editing
should support an external editor for large values. (The databases are
not directly reachable from a graphic terminal, and there is no HTTP
server running on them.)

psql is mostly fine for browsing, but I have some tables which have text
fields with a bad length distribution, and the nice and generally useful
padding in psql's output drastically inflates the output, to a point at
which it becomes completely unusable. And of course, data entry using
psql leaves something to be desired.
