Yes it is set in both the user's .profile and also in
/etc/profile. In both files it is set using:
LD_LIBRARY_PATH=/usr/sfw/lib:/usr/postgres/9.6-pgdg/lib
export LD_LIBRARY_PATH
That said, if I execute the following
su password
su postgres
echo $LD_LIBRARY_PATH
then echo returns blank. Echo will return the correct value only in
the usr login. The question then is if postgres is running as usr
postgres how does it know the value of LD_LIBRARY_PATH. Isn't there
another place where it must be set?
environment variables, including LD_LIBRARY_PATH gets dropped by su,
which is used to launch the postgres service.
but generally, using LD_LIBRARY_PATH is frowned on, instead, you should
link the applications with -R, or -Wl,-rpath and give it the path of the
libraries, so thats baked into the binary.
