Tests were failing with: Error: Process completed with exit code 143. This appears to mean that Github Actions killed the runner. See https://github.com/jackc/pgx/actions/runs/8216337993/job/22470808811 for an example. It appears Github Actions kills runners based on resource usage. Running tests one at a time reduces the resource usage and avoids the problem. Or at least that's what I presume is happening. It sure is fun debugging issues on cloud systems where you have limited visibility... :( fixes https://github.com/jackc/pgx/issues/1934
