Hello Simon, I'm really sorry for the inconveniences. Next time, I'll attach the patch with proper documentation, test and comments.

Since, this is redo(replay) feature, we can surely add this in installcheck. But, as Amit mentioned, it could be time-consuming. >> * wal_consistency_mask = 511 /* Enable consistency check mask bit*/ > > What does this mean? (No docs) I was using this parameter as a masking integer to indicate the operations(rmgr list) for which we need this feature to be enabled. Since, this could be confusing, I've changed it accordingly so that it accepts a list of rmgrIDs. (suggested by Michael, Amit and Robert) >> 1.

I'm modifying it accordingly. I'm calling this function after RmgrTable[record->xl_rmid].rm_redo. >> 5. Generalize the page type identification technique. > > Why not do this first? > At present, I'm using special page size and page ID to identify page type. But, I've noticed some cases where the entire page is initialized to zero (Ex: hash_xlog_squeeze_page). RmgrID and info bit can help us to identify those pages. -- Thanks & Regards, Kuntal Ghosh EnterpriseDB: http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
