Previously, isolationtester displayed SQL query results using some ad-hoc code that clearly hadn't had much effort expended on it. Field values longer than 14 characters weren't separated from the next field, and usually caused misalignment of the columns too. Also there was no visual separation of a query's result from subsequent isolationtester output. This made test result files confusing and hard to read. To improve matters, let's use libpq's PQprint() function. Although that's long since unused by psql, it's still plenty good enough for the purpose here. Like 741d7f104, back-patch to all supported branches, so that this isn't a stumbling block for back-patching isolation test changes. Discussion: https://postgr.es/m/582362.1623798221@sss.pgh.pa.us
