This will create a feature request which anybody can view and comment on.

Please describe your requested enhancement. Good feature requests will solve common problems or enable new use cases.

What you would like to accomplish:

Provide Cloud SQL with the ability to create triggers on insert new data. This trigger will help invoke other external applications to do some useful executions.

something like in

https://stackoverflow.com/questions/21634848/calling-external-program-from-postgresql-trigger/33494698#33494698

How this might work:

a new data will be inserted --> a trigger will execute in the database --> a external app will receive this trigger event

If applicable, reasons why alternative solutions are not sufficient:

This will help avoid including too many moving parts in the system and involve few products which in turn reduce the probability of errors.

Other information (workarounds you have tried, documentation consulted, etc):

we could use Pub-sub or Cloud Function
