I'm going to review this patch. Could you please rebase it? It
doesn't apply for me due to changes made in src/bin/psql/describe.c.
patching file src/bin/psql/describe.c
Hunk #1 FAILED at 1755.

5 out of 5 hunks FAILED -- saving rejects to file src/bin/psql/describe.c.rej
Also, please not that PostgreSQL 11 already passed feature freeze some
time ago. So, please adjust your patch to expect PostgreSQL 12 in the
lines like this:
+ if (pset.sversion >= 110000)
