pargs should work, but you'll probably have to run it as the postgres user or as root or you'll get "cannot examine <pid>: permission denied". pargs `/usr/bin/ps -opid -Upostgres | tail +2` I just did some tests on Solaris 9 and, curiously, whether /usr/ucb/ps shows the altered argument list or not appears to depend on the lengths of the original and replacement arguments: % ./foo x PID TT S TIME COMMAND 28106 pts/2 S 0:00 baz qux % ./foo xy PID TT S TIME COMMAND 28109 pts/2 S 0:00 ./foo xy As far as I can tell, for /usr/ucb/ps the show the replacement arguments, the sum of the lengths of the replacement arguments must be 2 or more greater than the sum of the lengths of the original arguments. I'm guessing that if the postmaster used a longer status message, then /usr/ucb/ps would show it. I'll test that the next time I rebuild PostgreSQL. -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faqs/FAQ.html
