OK, I forgot a bit about this past discussion. So let's say that we have a command, why not also allow users to use at will a marker %f to indicate the file name just completed? One use case here is to scan the file for the oldest and/or newest timestamps of the segment just finished to do some retention policy with something else in charge of the cleanup. The option name would be --end-segment-command? Any better ideas of names? -- Michael -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
