Hi,

Attached you can find version 7.8 of this patcheset. Changes since 7.7
include:
* Signature changes of the SQL changeset SRFs to support limits based on
  LSN and/or number of returned rows (pg_logical_slot_get_changes() et
  al) and to make parameter passing optional (by adding a DEFAULT '{}'
  to the variadic argument)
* heap_page_prune_opt() now decides itself which horizon to use,
  removing a good amount of duplicated logic
* GetOldestXmin() now has a Relation parameter that can be NULL instead
  of the former allDbs (existing in master) and systable (just this
  branch) parameters, also removing code duplication.
* pg_create_logical_replication_slot() is now defined in slotfuncs.c
* a fair number of cosmetic and comment changes

The open issues that I know of are:
* do we modify struct SnapshotData to be polymorphic based on some tag
  or move comments there?
* How/whether to change the exclusive lock on the ProcArrayLock in
  CreateInitDecodingContext()

Greetings,

Andres Freund
