Hi all, I'm wondering if there are anything to do to utilize a index when doing a range contains element query. I have tested this with 9.6 and 12.0.
I have a table with a timestamp column that has a btree index. I would like to do a query: SELECT * FROM table WHERE ts <@ tsrange($1, $2, '(]'); The index is not used and a seq scan is done instead. To use the index correctly I have to do the query like this: SELECT * FROM table WHERE ($1 IS null OR $1 < ts) AND ($2 IS null OR ts <= $2); I like the <@ syntax more. Is there something I can do differently? Maybe a different type of index instead? Thanks, -Lauri
