-* Add free-behind capability for large sequential scans (Bruce)
+* Add free-behind capability for large sequential scans (fadvise)
* Consider use of open/fcntl(O_DIRECT) to minimize OS caching
* Make blind writes go through the file descriptor cache
* Cache last known per-tuple offsets to speed long tuple access
* Acquire lock on a relation before building a relcache entry for it
* Research interaction of setitimer() and sleep() used by statement_timeout
* Add checks for fclose() failure
-* Change CVS $Id: TODO,v 1.1161 2003/10/26 04:43:55 momjian Exp $ to $PostgreSQL: pgsql/doc/TODO,v 1.1161 2003/10/26 04:43:55 momjian Exp $
