Hello, Please find attached a patch. As discussed, flag to denote compression and presence of hole in block image has been added in XLogRecordImageHeader rather than block header.
Following are WAL numbers based on attached test script posted by Michael earlier in the thread. WAL generated FPW compression on 122.032 MB FPW compression off 155.223 MB HEAD 155.236 MB Compression : 21 % Number of block images generated in WAL : 63637 Thank you, Rahila Syed ______________________________________________________________________ Disclaimer: This email and any attachments are sent in strictest confidence for the sole use of the addressee and may contain legally privileged, confidential, and proprietary data.
