I PostgreSQL-dokumentation, siges det at bruge /usr/ucb/ps med -ww-indstillinger for at få procesnavne i stedet for almindelige /usr/bin/ps, men det meste af informationen er også skjult af /usr/ucb/ps-indstillingen. Lad os se, hvordan du henter komplette postgres-procesnavne i solaris.
Nedenfor er mine postgres 9.1-instansprocesser på Solaris:
bash-3.00$ /usr/ucb/ps -awwx | grep postgres
7778 ? S 0:04 /Desktop/postgres/9.1-pgdg/bin/64/postgres -D /Desktop/postgres/9.1-pgdg/data
7779 ? S 0:01 /Desktop/postgres/9.1-pgdg/bin/64/postgres -D /Desktop/postgres/9.1-pgdg/data
7780 ? S 0:00 /Desktop/postgres/9.1-pgdg/bin/64/postgres -D /Desktop/postgres/9.1-pgdg/data
7781 ? S 0:00 /Desktop/postgres/9.1-pgdg/bin/64/postgres -D /Desktop/postgres/9.1-pgdg/data
7776 pts/5 S 0:00 /Desktop/postgres/9.1-pgdg/bin/64/postgres -D /Desktop/postgres/9.1-pgdg/data
Mere udvidet måde med pargs:
bash-3.00$ pargs `/usr/ucb/ps -awwx | grep postgres | awk '{print $1}'`
7778: /Desktop/postgres/9.1-pgdg/bin/64/postgres -D /Desktop/postgres/9.1-pgdg/data

7776 er postmaster daemon proces.
bash-3.00$ cat /Desktop/postgres/9.1-pgdg/data/postmaster.pid

Selvom det virker simpelt, tror jeg, det er værd at vide :).
