I've only tested it in the context of the buildfarm's script, which
implements this by dumping the given commands into a temp file
and invoking psql with -f. So that's fine with multiple DROP
DATABASE commands, but what 002_pg_upgrade.pl is doing isn't.
I guess you are running that in some way that the rest of us aren't.

I'm no perl maven either, but this looks fine to me.
Now that I look at it, I see that I missed a bet in the additions
to AdjustUpgrade.pm: rather than using IF EXISTS it should be
doing something more like the pre-existing logic
if ($dbnames{"contrib_regression_$bad_module"})
{
_add_st($result, 'postgres',
"drop database contrib_regression_$bad_module");
delete($dbnames{"contrib_regression_$bad_module"});
}
However, we'd inevitably hit the more-than-one-DB-to-drop problem
eventually, so better to fix that now. Please push your fix and
then I'll clean up the unnecessary DROPs.
