Обсуждение: Logging all queries
Вложения
I don't know if there is a better way, but you could enable log_connections and log_pid.
This way, you will get in your log file something like this:
2004-01-28 10:39:28 [79227] LOG: connection authorized: user=admin database=test
...
2004-01-28 10:39:33 [79227] LOG: statement: select * from people;
...
2004-01-28 10:39:35 [79227] LOG: statement: delete from people where name like 'f%';
...
you could use grep to filter connections (and their pids), and the you could grep again to find out what queries each pid executed.
If you are interested only in a particular table, then you could use a trigger AFTER INSERT OR UPDATE OR DELETE (not select), and there you could code a function to register what changes are being made to your table.
hope this helps

Hi All, I have set [log_statement=true] in the postgresql.conf file and now I have all the statements logged. But, there is a problem: Once I have more than one database, I had to know in which database a statement was executed on. The log file is full of: "select * from stuff", but as I have more than one database, how can I know where the [stuff] table is??????
