I ran this:

$ TESTS="postgresql zabbix guix-data-service" ./pre-inst-env guix build
-m etc/system-tests.scm 

And it did complete successfully!

/gnu/store/fz735r2c6rxdfjc214zvjayqin4i9aa4-postgresql-test
/gnu/store/h1pjyfp0bcfsswqcr4dvgsfzmj02p378-guix-data-service-test
/gnu/store/5xpdc8gmj5cbglm6dblasrl61m4w1xvz-zabbix-test

However, cuirass test did not work with an unrelated error:

$ TESTS="cuirass" ./pre-inst-env guix build -m etc/system-tests.scm 
guix build: warning: failed to load '(gnu tests cuirass)':
In procedure abi-check: #<record-type <cuirass-remote-worker-
configuration>>: record ABI mismatch; recompilation needed
Selected 0 system tests...

Does that sound good to you for the package upgrades?
