What: Use the github.com/jackc/pgx postgresql driver in place of github.com/lib/pq. Why: github.com/lib/pq has some problems with error handling and context cancellations (i.e. it might even issue queries or DML statements more than once! see https://github.com/lib/pq/issues/939). The github.com/jackx/pgx library appears not to have these problems, and also appears to be better engineered and implemented (in particular, it doesn't use "exceptions by panic"). It should also give us some performance improvements in some cases, and even more so if we can use it directly instead of going through the database/sql layer.
