hi,
I noticed this new param compute_query_id in pg14beta.
it is interesting as I was long wanting to identify a query with a unique id like we have for http requests etc so that we can trace the query all the way to shards via FDW etc.

but i cannot see them in the logs even after setting compute_query_id on.
i also read
compute_query_id_query for the same.
how is the compute_query_id actually calculated?
why does it show 0 in logs for random sql queries.
log_line_prefix = '%Q :'
0 :LOG: statement: select * from pg_stat_activity;
i mean pid already was doing the job to identify the query and its children even it logs,
but i know pid will get recycled.
tldr;
how is compute_query_id different from pid to identify some query running ?
can it be passed on to FDW queries ? for tracing etc ?
am i totally getting its use case totally wrong :)
