Hello list,
I am working on a Entity-Attribute-Value (EAV) database using
PostgreSQL 8.4.7. The basic problem is that when joining multiple
times different entities the planner thinks that there is vastly less
rows to join than there is in reality and decides to use multiple
nested loops for the join chain.
Did you consider using hstore instead?
I think in the PostgreSQL world, this is a better alternative than EAV and most
probably faster as well.
Regards
Thomas
