Hi

2018-05-10 12:23 GMT+02:00 a <372660931(at)qq(dot)com>:
Hi I would like to write a trigger that recorded every sql statement under the effected entry. So if it is possible to retrieve the sql statement within a trigger??

You can read a tom command from pg_stat_activity table

postgres=# select query from pg_stat_activity where pid = pg_backend_pid();
+------------------------------------------------------------------+
| query |
+------------------------------------------------------------------+
| select query from pg_stat_activity where pid = pg_backend_pid(); |
+------------------------------------------------------------------+
(1 row)

But this information is available only for top level query.

Pavel
