Google Sheets to PostgreSQL Integration

Question

I am using Google sheets as API and trying to integrate with the Postgres database. Looking for an open-source integration tool I found "Integromat" can move the data from Google sheets to Postgres. Trying to integrate both, succeeded with google sheets but Postgres database refuses to connect and gives me the below error.

connect ECONNREFUSED 127.0.0.1:5432

Have given access to Integormat port on the firewall defender as well. Can anyone help to able the Postgres database connection through Integromat
