I have figured out the issue with pgAgent both in Windows and Linux.
PgAgent seems to ignore pgpass.conf/.pgpass whenever it has 127.0.0.1
(127.0.0.1:5432:*:postgres:postgres) throws an error:
Could it be that hosts is not set up for?:
127.0.0.1 localhost
See below also.

hostaddr
"...
If hostaddr is specified without host, the value for hostaddr gives the
server network address. The connection attempt will fail if the
authentication method requires a host name.

So in your pg_hba.conf are you using a host name or IP address?
Looks like pgagent is using hostaddr w/o host and that will cause an
issue on psql also:
.pgpass
127.0.0.1:*:*:aklaver:some_pwd
psql "hostaddr=127.0.0.1 dbname=test user=aklaver"
Password:
Null display is "NULL".
psql (10.4)
SSL connection (protocol: TLSv1.2, cipher: ECDHE-RSA-AES256-GCM-SHA384,

Type "help" for help.
Adding a host name works:
psql "hostaddr=127.0.0.1 host=localhost dbname=test user=aklaver"
Null display is "NULL".
psql (10.4)
SSL connection (protocol: TLSv1.2, cipher: ECDHE-RSA-AES256-GCM-SHA384,

Using host alone works:
aklaver@tito:~> psql "host=127.0.0.1 dbname=test user=aklaver"
Null display is "NULL".
psql (10.4)
SSL connection (protocol: TLSv1.2, cipher: ECDHE-RSA-AES256-GCM-SHA384,

The solution could be update .pgpass to have (
localhost:5432:*:postgres:postgres ) and then pgagent works fine without
issues.
I think, pgagent is not inline with libpq.dll while passing host address
parameter. I have raised this concern with pgagent github where exactly
they need to change
the code in order for pgagent to be in line with psql program.

One more stupid question and then I'm out of ideas ...
Have you rebooted after changing the environment variable?
Global environment changes normally don't take effect until the user
logs out/in again. LocalSystem is not an interactive user - you
have
to restart the system to let it see environment changes. PITA.
Yes, I did. But no luck..I guess, we have to live with this problem
for pgagent running as a Local System account.
We need to run pgagent service as "Logon user account" and provide
user logon credentials for running pgagent service.
In Linux case, pgagent is not even reading .pgpass itself. The issue
here is that the logs (debug level log) are no help. It don't have
much information.
Which password file it is trying to read.
