* Use a row constructor comparison to avoid a filter
The original query had a WHERE condition that looked like:
(x > a) OR (x = a AND y < b)
This commit changes it to a compound comparison that, given the
lexicographical order it uses, is semantically the same:
(x, y) > (a, b)
This makes the plan in Postgres use an Index Cond instead of a Filter,
having two main performance improvements:
1. The query's time is more or less constant, not increasing every time
this query is executed. This is important because the query is executed
repeatedly until all posts are indexed.
2. The query's time is much shorter: while the original query eventually
takes 30s, hitting the timeout, the new one takes ~30ms.
Notice the difference in the plans below:
- the original query uses a `Filter` step, while the new one uses an
`IndexCond` + `Filter` step.
- the original query has a shared hit count of 40557115 (109GiB), while
the new one has a shared hit count of 13951 (109MiBA). This does not
show exactly how much data is read from disk, given it's a nested loop
node, but it gives us an idea of the amount of data processed in the
server.

* Go back to the old query for MySQL
As one could expect, the two databases have completely opposite
behaviours, and for MySQL, the old query is significantly faster than
the new one, exactly for the same reason than in Postgres, but the other
way around: the old query uses an Index range scan while the new one
would use a Filter.

We use the same name for hit/miss/invalidation metrics.
The downside is that now we have conflated a full cache purge
and a single cache key invalidation into a single label, but
the advantage is that it's easier to monitor the usage of a single
cache.
And moreover, duplicating the same string across multiple places
increases the chances of making a mistake. Centralizing the cache
name only at instantiation simplifies the code.
After this, we would be ready to use Redis.
