Hi, am I right that an XID is global across the whole DB cluster under the same $PGDATA? I am asking because in the WAL record, the first thing sent is an XLogRecord which contains
TransactionId xl_xid; and as the comment in access/xlog.h says: /* * The overall layout of an XLOG record is: * Fixed-size header (XLogRecord struct) * rmgr-specific data * BkpBlock * backup block data * BkpBlock * backup block data * ... And the BkpBlock structure contains the RelFileNode info, the triplet for tablespace/database/relation. Or is it completely backwards? I am asking this because I need to check TransactionIdDidCommit(XLogRecord->xl_xid) from the walreciver. Can I expect it to work on any xl_xid that walreceiver encounters?
