pgsql: Reduce cost of GetNotification by 2.5
...
By delaying the Layer join to the very end, we can cut the query costs from 540,836 to 219,477.
See Pull Request for details.

pgsql: use subquery to plan GetNotification query ( #182 )
...
This change enables the query planner to wait and sort the result set of
our query rather than attempting to re-use the layer table's index for
the ORDER BY clause. Because the result set is always small, this makes
queries that were previous tens of seconds, now tens of milliseconds.

database: Find the FeatureVersion we try to insert before doing any lock
...
This commit is issued in order to limit the bottleneck that the
exclusive database lock on Vulnerability_Affects_FeautreVersion
introduces, when we inserting FeatureVersions. This slowdowns a bit
the FeatureVersion insertion on a mostly empty database but should
increase a lot the throughput and parallelism on a populated database.

database: disable hash/merge joins in FindLayer
...
Our experiments have shown that PostgreSQL 9.4 makes bad
planning decisions about:
- joining the layer tree to feature versions and feature
- joining the feature versions to affected/fixed feature version and vulnerabilities
It would for instance do a merge join between affected feature versions (300 rows, estimated
3000 rows) and fixed in feature version (100k rows). In this case, it is much more
preferred to use a nested loop.
