Are you sure that you are trying to connect to the same database server?
Are you running psql and the other program on the same computer? Did you
try to use -h  for psql with your host?

psql -h 127.0.0.1 -d d3_jchem

Do you have ports forwarded on any of the machines?

It is not a file protection setting. The postgresql server owns all the
database files, and you can only access those files through the service.
Your problem is that you have multiple postgresql server instances
running. Either on the same machine, or on different machines.

Try to login with the postgresql superuser (pgsql or postgres). Then do
these:

select inet_server_addr()
select version()

Do this from both programs (psql and the other program) and compare the
results. Probably you will find out that you are connecting to two
different database instances.

Can you please tell us more about the other (non-psql) program? What is
that program? On what system have you installed that application? There
are some programs that run their own embedded postgresql server. It is
possible that you are running a program that uses an embedded PostgreSQL
server.

Any upper case characters in there and it's case folding maybe?
