Re: Same query, same data different plan

How identical is "identical"?

For example, does diff says that "pg_dump --schema-only" of DB1 and DB2 are perfectly identical?

And are the table counts identical?

Hi,

Thank you for responding. My question is not about the performance of a specific query. As I wrote, that is already solved.

My question is "how can it be that the same query run in two exactly the same databases can have different plans."

Hi,

Yes, I ran ANALYZE in both databases.

Please look at https://wiki.postgresql.org/wiki/Slow_Query_Questions to provide
