Where is pg_hba.conf

Re: Igor Korot 2017-08-13 <CA+FnnTwxiLXD2H_njPS6yf=nhjaE8vcwWFdVPPzbcuADmXTHgA@mail.gmail.com>

I need to modify the pg_hba.conf file to get access to the DB
remotely.

However, I can't find this file anywhere on the system.

Try "SHOW hba_file;".

Normally should reside in the data dir. My case below

armandps-MacBook-Air:~ armandp$ ps -fu postgres |grep data
502 29591 1 0 Thu09PM ?? 0:01.63 /Library/PostgreSQL/9.6/bin/postgres -D /Library/PostgreSQL/9.6/data

armandps-MacBook-Air:~ armandp$ ls -l /Library/PostgreSQL/9.6/data/pg_hba.conf
ls: /Library/PostgreSQL/9.6/data/pg_hba.conf: Permission denied
armandps-MacBook-Air:~ armandp$ sudo ls -l /Library/PostgreSQL/9.6/data/pg_hba.conf
-rw------- 1 postgres daemon 4248 Aug 10 21:17 /Library/PostgreSQL/9.6/data/pg_hba.conf

Is it possible that global search fails from a permission error ?

Hope this helps

Apparently it looks like the failure is from the permission.

So how do I enable it? Or it has to stay for "root" only?

Thank you.

Hope this helps

I am able to connec to the server locally with psql. I can also

Can someone please help?

Standard beginners error. If you forgot the ";" on the first line,
it'll process both lines as a single, erroneous command. Note the
"-#" prompt.

If you run into that situation again, hit ^C.

Hi,
OK, I found it under the root account.

Now I am modifying it as follows:

# TYPE DATABASE USER ADDRESS METHOD

# "local" is for Unix domain socket connections only
local all all md5
# IPv4 local connections:
host all all 192.168.1.3/32 md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres md5
#host replication postgres 127.0.0.1/32 md5
#host replication postgres ::1/128 md5

Should "METHOD" column be lept as 'md5' or as 'trusted' as in the link
I posted in the OP?

Thank you.

Also, I presume that the address in this file is the address of the
machine where the server is located, not the address from where the
connection is initiated.

Not according to the docs.

No. The addresses / network segments in the file specify from where
the client(s) can connect.

You can execute the query:

=# select setting from pg_settings where name = 'hba_file';
