My PostgreSQL default port is 5432, I want to change default port by using command line (in Windows 7).
I saw this solution before: https://stackoverflow.com/questions/187438/want-to-change-pgsql-port
I tried running the following command, but it failed:
postgres --p 5431
Could someone tell me how to change port in using command line?

Since you're on Windows and are probably starting PostgreSQL as a Windows service, you'll need to edit
postgresql.conf
(inside your data directory) to set the new port there, then restart the postgresql service using the Services control panel or (as an Administrator) thenet service
command.You can use a programmatic text editing tool to change
postgresql.conf
if you need to automate this. On a Linux/unix box you'd use a tool likesed
orawk
, but on Windows I imagine you'll be using VBS, powershell, or an add-on tool like Perl.You'll need to change the connection settings in tools like
PgAdmin-III
to use the new port.If you were starting PostgreSQL manually using
pg_ctl
you could set thePGPORT
environment variable or pass a config option on the command line. This won't work when you're launching it as a Windows service.
