I am experiencing a timing issue with the following query:
SELECT count(procpid) FROM pg_stat_activity WHERE usename='someuser'
 
If I execute the above query by the client who is user "someuser" and it is executed immediately after connecting I am getting two different results depending on the speed of the connection. If I connect to the database on a local area network of 100Mb/s and immediately execute the statement, I see the result of 0. If I connect to the same database over a slow connection, for example 115kb/s and immediately execute the statement, I see the result of 1.
 
Is this normal behaviour?
