8 | | -# Written for RedHat Linux but should apply to other Linux distributions. |
9 | | -# |
10 | | -# To be installed as /etc/rc.d/init.d/postgres.init |
11 | | -# Softlink into rc5.d to bring up with multiuser and networking: |
12 | | -# cd /etc/rc.d/rc5.d; ln -s ../init.d/postgres.init S98postgres |
13 | | -# |
14 | | -# Assumptions: |
15 | | -# - the postgres user is named "postgres" |
16 | | -# - the postgres user is running csh/tcsh |
| 8 | +# This version can log backend output through syslog using the local5 facility. |
| 9 | +# To enable this, edit /etc/syslog.conf to include a line similar to: |
| 10 | +# local5.* /var/log/postgres |
| 11 | +# and then set USE_SYSLOG to "yes" below |
17 | 12 | # |
| 13 | +#PGBIN="/opt/postgres/current/bin" # not used |
| 14 | +PGACCOUNT="postgres" # the postgres account (you called it something else?) |
| 15 | +POSTMASTER="postmaster" # this probably won't change |
| 16 | + |
| 17 | +USE_SYSLOG="yes" # "yes" to enable syslog, "no" to go to /tmp/postgres.log |
| 18 | +FACILITY="local5" # can assign local0-local7 as the facility for logging |
| 19 | +PGLOGFILE="/tmp/postgres.log" # only used if syslog is disabled |
| 20 | + |
| 21 | +PGOPTS="-B 256" |
| 22 | +#PGOPTS="-i -B 256" # -i to enable TCP/IP rather than Unix socket |
