Is that a verbatim copy of the error message? When I try intentionally
provoking this type of failure (by renaming the postgres executable out
of the way), 9.0 pg_ctl gives me this:
$ pg_ctl start
The program "postgres" is needed by pg_ctl but was not found in the
same directory as "/home/tgl/version90/bin/pg_ctl".
Check your installation.
$
The lack of double quotes and the lack of a full path to the pg_ctl
program make me wonder if you're running some really old copy of
pg_ctl instead of the 9.0 version as intended.
Anyway, if you didn't copy-and-paste exactly, what the error indicates
is that pg_ctl tried to execute "postgres -V" and didn't get any output.
What happens when you try that directly?
