Hi List. I have a list of bigint keys and I need to retrieve rows by these keys. Normally, I would split this list into pages of size 900 and perform several `SELECT ... WHERE key in($1,$2,...)`. However, the proprietary ORM we use can only produce this SQL: `SELECT ... WHERE (key=$1 or key=$2 or ...)`. Surprisingly, PostgreSQL planner treats these two SQLs differently: - ```select * FROM "audittrail$referencelogline" where id in ( 1 , 2 , 3 )``` Index Scan https://i.stack.imgur.com/dr8oz.png - ```select * FROM "audittrail$referencelogline" where id = 1 or id = 2 or id = 3``` A lot of "Bitmap Index Scan" for each value https://i.stack.imgur.com/dnErs.png Is it possible to configure PostgreSQL 12.16 to treat the second query as the first?
