Limiting the cases under which constraint ignoring works is certainly
fine by me, but I was assuming that we were trying to make it accessable
to any restore. If that's not true, then we don't need to worry about that
part of the issue.
As a side note, in the partial implementation I'd already done, I noticed
a potential problem if the person doing the alter table didn't have read
permissions on the pktable. I'd written it to bail and do the slow check
in that case (well actually in most error cases that didn't themselves
cause an elog), does anyone have a better idea?
