Hi,
From the document, it seems that PREPARE/EXECUTE works only in the same
session. I am wondering whether postgres can prepare a query (save the plan)
for difference backends.
I am working on a project which requires executing "psql -c 'query'" in
command line multiple times. Since the performance is critical, it would be
nice to prepare the same query first to avoid being parsed/optimized each
time. But psql opens a new backend each time, it looks like that
PREPARE/EXECUTE doesn't work. Is there any workaround?
Thanks
