I checked the commit log. About 001_basic.pl, it had been added at 2017 once but been reverted soon [1][2]. 322bec added the file again at 2022[3], so I chose 2022. About 002_pg_upgrade.pl, it has been added at the same time[3]. Definitively it should be 2022.
It is great to make sure each file has the Copyright and I see this patch has already been committed.
Just curious, is there a rule to add Copyright to Postgres? For example, if I run a command `grep -rn Copyright --include="*.pl" | awk -F ':' {'print $2, $1'} | sort -nr` inside postgres/src/bin, It seems most Copyright were added to the second line, but these two were added to the very beginning (of course, there are three other files following this pattern as well).
