Обсуждение: getcwd failing suddenly

Recently I have started seeing this error when starting the server.

shell-init: could not get current directory: getcwd: cannot access parent directories

Here is the command I use to start PostgreSQL.

su postgres -c "/usr/local/pgsql/bin/postmaster -S -D /usr/local/pgsql/data"

Did something change recently to cause this?  I find I can get around it
by changing the command to the following.

su postgres -c "cd /usr/local/pgsql; /usr/local/pgsql/bin/postmaster -S -D /usr/local/pgsql/data"

A quick glimpse scan shows no such error message in the Postgres
sources.  This must be coming out of your shell.  Protection change
on one of the ancestors of your home directory, maybe?

I forgot to mention that this happens on 3 different machines as I
upgrade to the latest PostgreSQL and each machine has a different
version of the OS.  I can't recall changing anything to do with
directory permissions but I certainly didn't change all 3.

Dumb question but I got bit by it before.  Is there a makefile.custom
nearby?  When I was cleaning up the docbook tags I put one in and it
had a couple of directories that didn't exist on my machine.  They 
probably existed on Tom Lockhart's machine, tho.  :)   I never noticed
it till the next time I built PostgreSQL.

You're starting it from a directory which user postgres does not have access
to. Therefore reading '..' (which the shell that su launched uses to determine
current directory) fails. It doesn't matter, although your solution works.
Other solution: Just use 'cd' instead of 'cd /usr/local/pgsql'
