In the course of upgrading a bunch of database clusters from 10 to 14 using pg_upgrade tool, some databases result in
thefollowing error recorded in pg_upgrade_dump_1.log, such that cluster upgrade fails.
FATAL: password authentication failed for user "postgres"
This was done on Microsoft Windows 11.
PostgreSQL 10 and 14 used are built using Visual Studio 2015.
Only a small number of database clusters has this problem, around 2 of 200.
It appears these database are used from earlier cluster upgrade from 9.4 to 10 as well.
It would be very helpful if there is any possible workaround to overcome this problem.
I attached a sample pg_upgrade_dump_1.log reported this error.
