Thanks for your reply Rob. Reading the below documentation link says the EVENT trigger is only supported for DDL commands. Is it not correct ?.

1) https://www.postgresql.org/docs/9.6/event-trigger-definition.html 

(An event trigger fires whenever the event with which it is associated occurs in the database in which it is defined. Currently, the only supported events are ddl_command_start, ddl_command_end, table_rewrite and sql_drop. Support for additional events may be added in future releases.).

2) Doesnt the trigger slow down inserts/update we are doing to the table ?. Does it slow down if we are reading the data using the API when we have a trigger in place ?.

Ah, right you are.  Are triggers off the table?  You would want to write the trigger function in some (trusted?) language with access to the outside
