Thanks to all for the feedback. I keep getting impressed by how
flexible PostgreSQL is.
Any ideas which query should perform better? I put together all the
suggested approaches below.
EXPLAIN ANALYZE of these queries in psql should give hard numbers. My
bet is on approach 3 to be the fastest since it does not require a join
node and has shorter target list / memory to move around.
