Attachments

Attached is the v49 patch set:
- Fixed the bug reported in [1].
- Addressed comments in [2] and [3].

I've split the patch into two, implementing the suggested idea in
comment #5 of [2] separately in 001:

Patch-001: Adds additional error reports (for all invalidation types)
in ReplicationSlotAcquire() for invalid slots when error_if_invalid =
true.
Patch-002: The original patch with comments addressed.
