feat(postgres): add postgres query config + db query optimizations

[guergabo]

Changes

1. Raw query flag for postgres connection.
2. Less frequent ticks for background jobs as default to not overload the database.
3. Larger transaction timeouts as default to not quit too soon.
4. Optimize queries by conditionally preparing statements for postgres aio store.
