With the addition of "pg_sync_replication_slots()", there is now a use-case for

Ran pgperltidy on the new TAP test file added.
While working on 4c2369ac5, I noticed there's close to as much code to
disallow BooleanTests in the form of "IS UNKNOWN" and "IS NOT UNKNOWN"
in partition pruning as it would take to allow pruning to work for
these.

Hi,
The --clean option of pg_restore allows you to replace an object before
being imported. However, dependencies such as foreign keys or views prevent
the deletion of the object. Is there a way to add the cascade option to
force the deletion?

sorry for the noise.
Don't worry, at least we know a weak point of partial paths estimation.

Hi,
I worked on using the currently proposed streaming read API [1] in ANALYZE.
The patch is attached. 0001 is the not yet merged streaming read API code
