Or you have used the test suite with an old installation that has the
same major version as the new installation, meaning that the filtering
was not happening, still you have detected some diffs?  It sounds to
me that we should just apply the filters to the dumps all the time if
you have used matching versions.  The filtering would remove only the
comments, some extra newlines and replace the CRLFs in this case.

Yes, my case is with the same version, literally:
build>echo create database regression>c:\temp\dump.sql
build>set olddump=c:\temp\dump.sql& set 
oldinstall=%CD%/tmp_install/usr/local/pgsql& meson test pg_upgrade/002_pg_upgrade

So removing the condition "if ($oldnode->pg_version != $newnode->pg_version)"
works here as well, but maybe switching the file mode (to preserve EOLs
produced by pg_dump) in the block "After dumping, update references ..."
is more efficient than filtering dumps (on all OSes?).

Best regards,
Alexander
