The deal on Solaris is this: There's SysV-style ps at /usr/bin/ps, and there's BSD-style ps at /usr/ucb/ps. The most obvious differences are the different argument style and the different output format. In true BSD style, the /usr/ucb/ps display can be changed by assigning argv[x] = "whatever". In true SysV style, the /usr/bin/ps display can (presumably) be changed with strcpy(argv[0], "whatever"). The old (pre-7.1) code only worked for BSD and had an exception case for Linux. The new code is mostly adopted from Sendmail. So in pre-7.1 you could get /usr/ucb/ps to work, while Sendmail apparently tried to get the SysV-style ps to work -- and failed(?). (This is generally the right direction, because the /usr/ucb stuff is obsolescent on Solaris, only for compatibility with SunOS 4.) The consequence should be: 1. check if sendmail works with /usr/bin/ps 2. a) if yes, figure out what got lost in PostgreSQL 2. b) if no, make the Solaris case in ps_status.c use the BSD approach -- Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/
