Hide db name and user name in process list arguments

Hi,

On Unix systems Postgres process list can be  accessible through ‘ps’ utility:

ps auxww | grep ^postgres

$ ps auxww | grep ^postgres

postgres   960  0.0  1.1  6104 1480 pts/1    SN   13:17   0:00 postmaster -i

postgres   963  0.0  1.1  7084 1472 pts/1    SN   13:17   0:00 postgres: stats buffer process   

postgres   965  0.0  1.1  6152 1512 pts/1    SN   13:17   0:00 postgres: stats collector process   

postgres   998  0.0  2.3  6532 2992 pts/1    SN   13:18   0:00 postgres: tgl runbug 127.0.0.1 idle

postgres  1003  0.0  2.4  6532 3128 pts/1    SN   13:19   0:00 postgres: tgl regression [local] SELECT waiting

postgres  1016  0.1  2.4  6532 3080 pts/1    SN   13:19   0:00 postgres: tgl regression [local] idle in transaction

And each client connection has its command line which displays in form:

postgres: user database host activity

Is there any way to hide dbname and user name in displayed arguments of client connections?

Thanks,

Irina
