Subject: Fix examples of how to use "su" while starting the server.
X-Git-Tag: REL9_3_BETA1~881
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7d8cbeb0c3f48c6c204b742b6891a9e5e5031d15;p=postgresql

Fix examples of how to use "su" while starting the server.

The syntax "su -c 'command' username" is not accepted by all versions of
su, for example not OpenBSD's.  More portable is "su username -c
'command'".  So change runtime.sgml to recommend that syntax.  Also,
add a -D switch to the OpenBSD example script, for consistency with other
examples.  Per Denis Lapshin and Gábor Hidvégi.
