PostgreSQL version: 9.1.2
Operating system: Mac OS X 10.7
Description:=20=20=20=20=20=20=20=20
for a stand alone app that uses postgres, the app installer invokes the
shell script installbuilder.sh for the "unattended" install of postgres.
The pg installer creates a user "PostgreSQL" that is not hidden, but does
not create a hidden account "postgres". As a result, the invocation of
pg_ctl fails. Error is "unknown login: postgres".=20
