Обсуждение: Addition of PostgreSQL::Test::Cluster::pg_version()

Hi all,
(Added Andrew in CC.)

While working more on expanding the tests of pg_upgrade for
cross-version checks, I have noticed that we don't expose a routine
able to get back _pg_version from a node, which should remain a
private field of Cluster.pm.  We already do that for install_path, as
of case added by 87076c4.

Any objections or comments about the addition of a routine to get the
PostgreSQL::Version, as of the attached?

Thanks,

I haven't tested the patch, but +1 on the idea.

Looks ok. PostgreSQL::Version is designed so that the object behaves
sanely in comparisons and when interpolated into a string.


cheers

I saw that, and that's kind of nice when it comes to write
version-specific code paths in the tests ;)

Okay, I have applied this thing.  I'll move back to my business with
the tests of pg_upgrade...
