Re: Select on partitioned table is very slow

Dear Depesz, Laurenz,

Thanks very much for the fast responses. They are actually correct and saved me a lot of time. I couldn't test the cast from the Java test but this is something I can deal with later on (most probably updating the column types to text in the database side instead). But what I could do was reproduce the same problem in the psql console using the cast in the other way. This sentence:

explain analyze select logical_identifier, version_id, lastproduct
    FROM test_product_ui_partition.product_ui pui
    WHERE pui.mission_id='urn:esa:psa:context:investigation:mission.em16'::citext
    AND pui.logical_identifier='urn:esa:psa:em16_tgo_frd:data_raw:frd_raw_sc_n_20220729t000000-20220729t235959'::citext;

explain analyze select logical_identifier, version_id, lastproduct    FROM test_product_ui_partition.product_ui pui       WHERE pui.mission_id='urn:esa:psa:context:investigation:mission.em16'::text       AND pui.logical_identifier='urn:esa:psa:em16_tgo_frd:data_raw:frd_raw_sc_n_20220729t000000-20220729t235959'::text; 

::text?
