Erro.:

Server doesn’t listen
The server doesn’t accept connections: the connection library reports
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host “127.0.0.1” and accepting TCP/IP connections on port 5432?
If you encounter this message, please check if the server you’re trying to contact is actually running PostgreSQL on the given port. Test if you have network connectivity from your client to the server host using ping or equivalent tools. Is your network / VPN / SSH tunnel / firewall configured correctly?
For security reasons, PostgreSQL does not listen on all available IP addresses on the server machine initially. In order to access the server over the network, you need to enable listening on the address first.
For PostgreSQL servers starting with version 8.0, this is controlled using the “listen_addresses” parameter in the postgresql.conf file. Here, you can enter a list of IP addresses the server should listen on, or simply use ‘*’ to listen on all available IP addresses. For earlier servers (Version 7.3 or 7.4), you’ll need to set the “tcpip_socket” parameter to ‘true’.
You can use the postgresql.conf editor that is built into pgAdmin III to edit the postgresql.conf configuration file. After changing this file, you need to restart the server process to make the setting effective.
If you double-checked your configuration but still get this error message, it’s still unlikely that you encounter a fatal PostgreSQL misbehaviour. You probably have some low level network connectivity problems (e.g. firewall configuration). Please check this thoroughly before reporting a bug to the PostgreSQL community.

uma dica… verifique nos arquivos pg_hba.conf e postgresql.conf e verifique se sua maquina está configurado corretamente lá. Se estão suas informações de IP e porta corretamente.

como saber se esta certo ?

esse arquivo pg_hba parece estar coerente… e o outro arquivo? poste ele

tem alguma coisa haver com o msconfig? depois que desativei alguns itens ocorreu esse error.

Seria isso o config

PostgreSQL configuration file

-----------------------------

This file consists of lines of the form:

name = value

(The ‘=’ is optional.) White space may be used. Comments are introduced

with ‘#’ anywhere on a line. The complete list of option names and

allowed values can be found in the PostgreSQL documentation. The

commented-out settings shown in this file represent the default values.

Please note that re-commenting a setting is NOT sufficient to revert it

to the default value, unless you restart the server.

Any option can also be given as a command line switch to the server,

e.g., ‘postgres -c log_connections=on’. Some options can be changed at

run-time with the ‘SET’ SQL command.

This file is read on server startup and when the server receives a

SIGHUP. If you edit the file on a running system, you have to SIGHUP the

server for the changes to take effect, or use “pg_ctl reload”. Some

settings, which are marked below, require a server shutdown and restart

to take effect.

Memory units: kB = kilobytes MB = megabytes GB = gigabytes

Time units: ms = milliseconds s = seconds min = minutes h = hours d = days

#---------------------------------------------------------------------------

FILE LOCATIONS

#---------------------------------------------------------------------------

The default values of these variables are driven from the -D command line

switch or PGDATA environment variable, represented here as ConfigDir.

#data_directory = ‘ConfigDir’ # use data in another directory
# (change requires restart)
#hba_file = ‘ConfigDir/pg_hba.conf’ # host-based authentication file
# (change requires restart)
#ident_file = ‘ConfigDir/pg_ident.conf’ # ident configuration file
# (change requires restart)

If external_pid_file is not explicitly set, no extra PID file is written.

#external_pid_file = ‘(none)’ # write an extra PID file
# (change requires restart)

#---------------------------------------------------------------------------

CONNECTIONS AND AUTHENTICATION

#---------------------------------------------------------------------------

- Connection Settings -

#listen_addresses = ‘localhost’ # what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to ‘localhost’, ‘*’ = all
# (change requires restart)
#port = 5432 # (change requires restart)
#max_connections = 100 # (change requires restart)

Note: increasing max_connections costs ~400 bytes of shared memory per

connection slot, plus lock space (see max_locks_per_transaction). You

might also need to raise shared_buffers to support more connections.

#superuser_reserved_connections = 3 # (change requires restart)

- TCP Keepalives -

see ‘man 7 tcp’ for details

# 0 selects the system default
#tcp_keepalives_interval = 0 # TCP_KEEPINTVL, in seconds;
# 0 selects the system default

ERROR REPORTING AND LOGGING

#---------------------------------------------------------------------------

- Where to Log -

#log_destination = ‘stderr’ # Valid values are combinations of
# stderr, syslog and eventlog,
# depending on platform.

This is used when logging to stderr:

#redirect_stderr = off # Enable capturing of stderr into log
# files
# (change requires restart)

These are only used if redirect_stderr is on:

#log_directory = ‘pg_log’ # Directory where log files are written
# Can be absolute or relative to PGDATA
#log_filename = ‘postgresql-%Y-%m-%d_%H%M%S.log’ # Log file name pattern.
# Can include strftime() escapes
#log_truncate_on_rotation = off # If on, any existing log file of the same
# name as the new log file will be
# truncated rather than appended to. But
# such truncation only occurs on
# time-driven rotation, not on restarts
# or size-driven rotation. Default is
# off, meaning append to existing files
# in all cases.
#log_rotation_age = 1d # Automatic rotation of logfiles will
# happen after that time. 0 to
# disable.
#log_rotation_size = 10MB # Automatic rotation of logfiles will
# happen after that much log
# output. 0 to disable.

These are relevant when logging to syslog:

#syslog_facility = ‘LOCAL0’
#syslog_ident = ‘postgres’

# debug5
# debug4

# warning
# error
# log
# fatal
# panic

#log_error_verbosity = default # terse, default, or verbose messages

#log_min_error_statement = error # Values in order of increasing severity:
# debug5
# debug4
# debug3
# debug2
# debug1
# info
# notice
# warning
# error
# fatal
# panic (effectively off)

Olá amigo,

Não vi nada de estranho na configuração do seu servidor, pelo que vi está usando windows, provavelmente o serviço do seu postgresql não está rodando

Vamos lá

Aperte Windows+R

digite: services.msc e aperte ok

Procure por postgresql e inicie o serviço.

Veja se isso resolve, a propósito qual a Versão do seu SO e do seu PosrgreSQL?

Abços
