In the recent codebase update (commit 8bf6fbd, 2023-12-09), a new unit testing framework written entirely in C was introduced to the Git project aimed at simplifying testing and reducing test run times. Currently, tests for the reftable refs-backend are performed by a custom testing framework defined by reftable/test_framework.{c, h}. Port reftable/pq_test.c to the unit testing framework and improve upon the ported test. The first patch in the series is preparatory cleanup, the second patch moves the test to the unit testing framework, and the rest of the patches improve upon the ported test.
