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()

Andres Freund
