Thanks for implementing this! This has been #1 on my PG annoyances list since forever. I had even tried to patch it 10½ years ago, but ever managed to get that patch to submittable quality.
Now, is there a chance that we could make this the default? Having psql print a whole screen of ------------ minus characters doesn't seem very useful as default behavior.
I see upthread that Pavel was objecting to that because pspg doesn't understand it. But since the expanded format is a one-column output, and the only thing pspg needs to know is the maxium line length, I'd think pspg could just look at each line, and update the maximum as it reads the input anyway.
pspg requires all lines to have the same width. It can do some corrections - but it is hard to detect wanted differences or just plain text format.
can be nice to have the first invisible row with some information about used formatting. pspg does some heuristic but this code is not nice and it is fragile.
