Hi,
My Database have a lot of locks not granted every moments in a day.
Can I create a view that returns someting like this ?
User Granted Table Who_is_locking_me PID
---- ------- ----- ----------------- ---
joe f foo frank 1212
jeff f foo frank 1313
ann f foo frank 1414
frank t foo 1111
(...)
(Or the locked transactions, if the table cold't be retrived)
You can look up more data about a backend by joining pg_locks to
pg_stat_activity, using the PID (I think it's called procpid on one view
and pid on the other).
Hi,
But pg_stat_activity joined with pg_locks only give me informations
about the lock itself.
Realy, I want a (possible) simple information: Who is locking me ?
Today, I *presume* this information by manually search the pg_locks:
1) Search for the locked tables
2) Search for all lock GRANTED to this tables
3) Generally, the older PID is the locker
Not so smart, I think. :)
Best regards,
Alexandre
