Thanks for updates.
However, I found that functions like LockHeldByMe(), CheckRelationOidLockedByMe()
and LWLockHeldByMe() have been used only for the debug build. Functions like
ProcArraySetReplicationSlotXmin() and MarkAsPrepared() can remove the flag from
the argument but they are retained till now.
Based on that, I suggest adding new argument (or add new Ex function for bank branches)
and do the assertion check when the assertion is enabled in this build. Thought?
