Maybe we need to make AdjustUpgrade just look at the major version,
something like:
$old_version = PostgreSQL::Version->new($old_version->major);
It seems like that does work, but if we do that, then we also need to
change this line:
if ($old_version lt '9.5')
to if ($old_version < '9.5')
otherwise you get some really mysterious failures about trying to drop
public.=>, which is in fact no longer accepted syntax since 9.5; and the
stringwise comparison returns the wrong value here.
That seems odd. String comparison like that is supposed to work. I will do some tests.
TBH I'm getting a sense of discomfort with the idea of having developed
a Postgres-version-number Perl module, and in the only place where we
can use it, have to settle for numeric comparison instead.
These comparisons only look like that. They are overloaded in PostgreSQL::Version.
The result you report suggest to me that somehow the old version is no longer a PostgreSQL::Version object. Here's the patch I suggest:
diff --git a/src/test/perl/PostgreSQL/Test/AdjustUpgrade.pm b/src/test/perl/PostgreSQL/Test/AdjustUpgrade.pm
index a241d2ceff..d7a7383deb 100644

Do you still see errors with that?
