Ola, com que método você ta tentando realizar essa conexão ?

• Primeiramente, você deve delegar as permissões para uma outra determinada rede acessar sua base local, ou permissão 'all' de acesso remoto a mesma. Permissão esta continda no arquivo pg_hba.conf, localizado dentro da pasta data na raiz da instalação do postgre.

Segue alguns exemplos de como configurar o mesmo.

Allow any user on the local system to connect to any database under

any user name using Unix-domain sockets (the default for local

connections).

#

TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD

local all all trust

The same using local loopback TCP/IP connections.

#

TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD

host all all 127.0.0.1 255.255.255.255 trust

Allow any user from any host with IP address 192.168.93.x to connect

to database "template1" as the same user name that ident reports for

the connection (typically the Unix user name).

#

TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD

host template1 all 192.168.93.0 255.255.255.0 ident sameuser

Allow a user from host 192.168.12.10 to connect to database

"template1" if the user's password is correctly supplied.

#

TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD

host template1 all 192.168.12.10 255.255.255.255 md5

In the absence of preceding "host" lines, these two lines will

reject all connection from 192.168.54.1 (since that entry will be

matched first), but allow Kerberos V connections from anywhere else

on the Internet. The zero mask means that no bits of the host IP

address are considered so it matches any host.

#

TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD

host all all 192.168.54.1 255.255.255.255 reject host all all 0.0.0.0 0.0.0.0 krb5

Allow users from 192.168.x.x hosts to connect to any database, if

they pass the ident check. If, for example, ident says the user is

"bryanh" and he requests to connect as PostgreSQL user "guest1", the

connection is allowed if there is an entry in pg_ident.conf for map

"omicron" that says "bryanh" is allowed to connect as "guest1".

#

TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD

host all all 192.168.0.0 255.255.0.0 ident omicron

If these are the only three lines for local connections, they will

allow local users to connect only to their own databases (databases

with the same name as their user name) except for administrators and

members of group "support" who may connect to all databases. The file

$PGDATA/admins contains a list of user names. Passwords are required in

all cases.

#

TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD

local sameuser all md5 local all @admins md5 local all +support md5

The last two lines above can be combined into a single line:

local all @admins,+support md5

The database column can also use lists and file names, but not groups:

local db1,db2,@demodbs all md5
