Re: Dynamic queries for Partitions

Hello Bill,

if I understand correctly, you need to have constraint exclusion turned on and be careful about types - types in WHERE condition should be the same as those with CHECK constraint in partitioned table. Then you won't need 2 steps, but just one - one SELECT from master table fits all. Details are in the PostgreSQL documentation (Partitioning).
