Обсуждение: List of currently connected users

Hello,
  Is it possible to show a list of all currently connected users into the
specific postgres database (what's the command)?

  Thanks,
  Julian

mailto:juleni@seznam.cz

ps -ef | grep post

postgres  4571 27462  0 12:02 ?        00:00:00 postgres: medi Test1
[local] idl

says, some guy name 'medi' is connected to database 'Test1' via process
ID 4571.

or

psql -c "select * from pg_stat_activitity"

 datid | datname | procpid | usesysid | usename | current_query
-------+---------+---------+----------+---------+---------------
 16556 | Test1   |    4571 |      100 | medi    |
(1 row)

Which says some guy named 'medi' is connecting to database 'Test1' via
process ID 4571.

Isn't PG cool....

It's getting that way.
I currently use mySQL at my work and I'm thinking about using PG for
a personal project so I've been lurking on the list.  I must say, I've been
seeing a few things that have been pretty cool.  Lots I've been aching to
ask about but haven't yet because I haven't fully delved into the docs.
But I must say, I like what I've been seeing so far. :p
