How to allow remote connections to your local development PostgreSQL server?
Find the pg_hba.conf file for your local development PostgreSQL server instance.
If you know the PostgreSQL base directory then typically this conf file will be in (base)/PostgreSQL/9,0/data/pg_hba.conf
If you don't know the base directory, then use Windows File Search, or with Cygwin try find . -type f | grep pg_hba.conf
Add the following line at the bottom of your pg_hba.conf file
host all all xxx.xxx.xxx.x/24 trust
