I have been working on optimizing a PostgreSQL server for weekly updates where data is only updated once a week then for the remaining portion of the week the data is static. So far I have set fsync to off and increased the segment size among other things. I need to ensure that at the end of the update each week the data is in state where a crash will not kill the database.
Right now I run "sync" afte the updates have finished to ensure that the data is synced to disk but I am concerned about the segment data and anything else I am missing that PostgreSQL explicitly handles. Is there something I can do in addition to sync to tell PostgreSQL exlplicitly that it is time to ensure everything is stored in its final destionation and etc?
