I'm finally returning to this 14 month old thread:
(was: Re: BUG #16045: vacuum_db crash and illegal memory alloc after pg_upgrade
from PG11 to PG12)

I meant to notice if the binary format is accidentally changed again, which was
what happened here:
7c15cef86 Base information_schema.sql_identifier domain on name, not varchar.
I added a table to the regression tests so it's processed by pg_upgrade tests,
run like:
| time make -C src/bin/pg_upgrade check oldsrc=`pwd`/11
oldbindir=`pwd`/11/tmp_install/usr/local/pgsql/bin
I checked that if I cherry-pick 0002 to v11, and comment out
old_11_check_for_sql_identifier_data_type_usage(), then pg_upgrade/test.sh
detects the original problem:
pg_dump: error: Error message from server: ERROR: invalid memory alloc request
size 18446744073709551613
I understand the buildfarm has its own cross-version-upgrade test, which I
think would catch this on its own.
These all seem to complicate use of pg_upgrade/test.sh, so 0001 is needed to
allow testing upgrade from older releases.
e78900afd217fa3eaa77c51e23a94c1466af421c Create by default sql/ and expected/
