I have an oracle foreign table that holds arbitrary tasks, when a task gets
updated the "time_update" field will change. I want to detect when the field
changes so I can insert the values in a local table for completed tasks. Can
postgresql detect changes in a foreign table so a trigger can be invoked? I
am new to postgrwsql so any examples or education on what steps to take to
complete tjos would be greatly appreciated!
