drop table doesn't fire ddl_command_end event trigger

2017-09-25 10:42 GMT-03:00 <sanyamjain22@live.in>:

I have enable ddl_command_end trigger on a table.I can see fired events when
ddl type is alter or create but drop is not catched. But in description
https://www.postgresql.org/docs/9.6/static/event-trigger-matrix.html
it is mentioned that drop table will also generate ddl_command_end trigger.

You don't show a test case. It works for me.

tg_tag,

Digite "help" para ajuda.
