Probably reading my logs wrong or misunderstanding something basic but my temp_buffers is 512MB and I see things in the log like:

2023-06-23 18:02:44 UTC:172.31.21.22(40866):woliver@db:[25473]:LOG: temporary file: path "base/pgsql_tmp/pgsql_tmp25473.135", size 255107072

Wondering why 255mb is being written to disk rather than using RAM?
