Following up on this, I very often have to create PLPgSql functions to
workaround this problem: create one (or several) temp table(s) (with ON
COMMIT DROP), analyze it/them and create indices on some field(s).
Being able to write something like:
WITH xxx AS MATERIALIZED ANALYZED INDEXED ON field1 (
SELECT DISTINCT myfield AS field1
FROM table1
)
SELECT field2
FROM table2
JOIN xxx USING(field1);
would help a lot in some cases. Of course, the syntax is just a thought
but the general idea is there.
