Thread: Log all queries before migration ?

Hi guys,

We have some storage problem on our dedicated server and we have to migrate.
Do you know how can I log all queries in order to have no downtime during
migration ?

I tried many options on the conf, but i never find the good one. I didn't
find out to generate .sql file with all queries.

Thank you a lot for your help !

Hi guys,

In fact, I would like to copy a table and then, when everything is finish,
execute all inserts and updates since the beginning of the copy.

The biggest problem with the log at this time it's the query.
All my queries are not runnable.

When I log, I see this kind of queries :
"duration: 0.046 ms  parse <unnamed>: UPDATE user SET money = money + $1
WHERE id = $2"

But I would like to have only : "UPDATE user SET money = money + 100 WHERE
id = 1281012"

This is our postgresql.conf :
log_destination = 'csvlog'
logging_collector = on
log_min_duration_statement = 0
log_statement = mod
log_directory = '/media/hdd/log_queries'
log_filename='log_insert.log'
log_file_mode = 0600
log_error_verbosity = verbose


What do we have to change ?

Thank you a lot for your help !
