I saw the note in the docs that to_char(interval, text) is deprecated, and will be removed. I searched the archives and saw more mentions of this, but no real explanation as to how it is planned for us to get consistent output formatting when querying a column containing interval data. For example, if you have data in an "interval" column, and just SELECT it (without special formatting), you get things like: 00:05:00 3 days 1 day 04:00:00 3 days 03:10:00 Currently, if I use something like: to_char(t.estimated_time, 'DD HH24:MI'), I seem to get consistent results that my program can easily deal with: 00 00:05 00 00:10 01 04:00 00 01:05 03 03:10 Can someone please explain if there is something else I should be using, or what the plans actually are for handling this in future? Should I just store the value in seconds as an integer and handle everything myself?
