I have two identical databases running in the same instance of Postgresql. Ran
analyze on both. Running the same query I'm getting different plans, one x10 slower.
Although I have solved my problem by re-writing the query, I want to understand why
this is happening. If the configuration, Postgresql version, schema and data are the
same, what other factors is the planner considering?
