Hi. I'm wondering about possibilities for taking action when a table is
renamed.
Specifically in this case, I'm using table_log, which when you use it on
a table creates a new table, sequence and index that is tied to the
table name. Of course, if the oriignal table is renamed, the other
relations aren't. So I rename table to table_old, and then create a new
version of table, but the table logging fails because of the
already-existing relations that table_log created.
I could of course rename them manually, or create a function to do it,
but that would still need to be manually invoked. I haven't really used
listen/notify--I assume it could do this, but there would need to be
some kind of process actively listening?
Something like a trigger on the table rename would be ideal for my
purposes. Anything like that possible? Thanks!
