Right, that's not generally an available option for us.  The two
approaches I've had success with are a) bypassing test-during-build, and
b) bootstrapping from earlier versions.  Towards the end of this page is
a section on handling circular dependencies that explain these two:

    https://github.com/canonical/ubuntu-maintainers-handbook/blob/main/ProposedMigration.md1

In this case, it doesn't look like the dependency is due to testing so
option (b) may be worth looking at.  It appears that g-g-j-pgtype
used to depend on g-g-j-pgx-dev, at version 1.10.0-3, which is currently
available in kinetic.

So, I think the bootstrap solution might be:

  1. Verify that g-g-j-pgtype (1.10.0-3) actually does build
     successfully against g-g-j-pgx-dev (3.6.2-2).  (This is probably
     best to verify in a PPA.)  If so, then...

  2. Request an Archive Admin to delete from -proposed:
     - golang-github-jackc-pgtype (1.10.0-4) source & binary
     - golang-github-jackc-pgx (4.15.0-4) source & binary

  3. Prepare and upload g-g-j-pgtype (1.10.0-3), and verify it
     builds ok.  Then proceed with syncpackage on both packages to pull
     in the newer versions.

If step #1 does *not* work, then the problem is more complex.  It might
be worth checking in with the Debian maintainer for ideas at that point.
