Hi all,
There are some reason to "-i, --ignore-version" option doesn't appear in
pg_dump help?

Because it's obsolete option, I think.

You're correct... looking at the source code:
421 case 'i':
422 /* ignored, deprecated option */
423 break;
Thanks!

Yeah, see commit c22ed3d523782c43836c163c16fa5a7bb3912826.
Considering we shipped that in 8.4, maybe it's time to remove all
trace of those switches. We'd still have to wait a couple releases
before it'd be safe to use -i for something else, but it'd be a start.

This is only set when TAS is defined, so we can just check whether
TAS is defined directly instead.
