Hi: I am using the wonderful lateral query feature like the following
select * from generate_series (1,100000,5) T(t), lateral (select * from P where t between t and t + 3) P is a parent table of a hundred partitions the idea is to for each t value from 1 to 100000 with step of 5, get rows from P (in one or two of its partitions) that between the current value of t and t+3, so each lateral select should only index scan one or two partitons but the query plan shows that each will scan all hundred paritions, I think due to its unable to determine the range since the query is select * from P where t between t and t + 3 as "t" is unknown at the time of parsing. How to force query planner "dynamically" generate plan to for each lateral select query as "t" changes. Thanks
