Обсуждение: improving \dt++ in psql

Hi


I tried to start writing a patch to add "Total Size" column to \dt++ output.

in src/bin/psql/describe.c we have this

listTables(
const char *tabtypes,
const char *pattern,bool verbose,bool showSystem)


I was (as a long time Pg user) dead sure that psql really sometimes
cares about the number of plus signs that you add to meta-command

So why this particular function interface has boolean "verbose" parameter?

Can't we have higher levels of "verbosiness"?


thanks,
Filip

No, it never has done so AFAIK.

I think that for most commands, two levels of verbosity are already
complicating the code in describe.c about as much as it can stand :-(
Things like the infrastructure to mark particular columns as translatable
would really need some significant work if we want to adopt multiple
pluses as a standard design element.
