Обсуждение: how to get unique identifier for a client
hi all is there a way to get a unique identifier for a client? something like a machine id. session_user does not seem to work since a user can log on to many workstations. been through the list so i'm not searching for getting the ip address since the list said something like it's not supported in unix-sockets, though i'll take it since i'm using postgres in windows environment. thanks in advance :)
I would gather all possible inputs of data that you can use for it.
Will the data be stored in one place for all customers ? if so - you'll be okay with uuid of some sort, as primary key on a table.
if you need data to depend on outside data, either write a query, that would generate it, taking those outside params as input, or write C procedure, that will gather that data, and return some unique key.
So it all depends on what are you actually trying to achieve.

If not, then select * from pg_stat_activity should have uniquely identifying information in it.
hi! unfortunately the unique identifier must not change from connection to connection, so that there can be a meaningful review of the usage table. is there a similar problem that you've encountered in the past that has this requirement?
