Independent of the thrust of my question - why aren't we adding a
'force-v2' option to libpq? A test that basically does something like
postgres[22923][1]=# \setenv PGFORCEV2 1
postgres[22923][1]=# \c
You are now connected to database "postgres" as user "andres".
postgres[22924][1]=>
seems easy enough to add, in fact I tested the above.

And the protocol coverage of the v2 protocol seems small enough that a
single not too large file ought to cover most if it quite easily.
