PostgreSQL connection string special character issues

Hi I'm having an issue connecting to a PostgreSQL SB where the password contains special characters.

if my password is abc#123, and I create a connection string like:
`postgres://myusername:abc%23123@db.host/mydb`

where **#** is escaped to be **%23** as required by PostgreSQL. I get the following error when I try to connect:

`const db = sql.open('postgres', 'postgres://myusername:abc%23123@db.host/mydb');`

`ERRO[0005] GoError: parse "postgres://myusername:abc%!?(MISSING)k@db.host/mydb": invalid port ":abc%!"(MISSING) after host`

How should can I connect to PostgreSQL DBs where a password contains a special character? Please help.
