Password not parsed correctly by stork-tool

Documentation states stork-tool cert-export --db-url postgresql://user:pass@localhost/dbname -f srvcert -o srv-cert.pem but it's not working with complex passwords (didn't try with the simple one so maybe it's not working at all ;) ).

# stork-tool cert-export --db-url 'postgresql://stork:R(cBBz3eokjDuZ>l8IYGF6@localhost/stork' -f cakey 
FATA[2021-11-22 23:03:22]             main.go:26    cannot parse db URL     

but it works with psql native command line

# psql 'postgresql://stork:R(cBBz3eokjDuZ>l8IYGF6@localhost/stork'
psql (12.8 (Ubuntu 12.8-0ubuntu0.20.04.1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

stork=> \q

So the parsing of the URL should be done in a better/different way

Another issue is that without a password in postgresql URI "stork-tool" should ask for password but it throws error instead.

# stork-tool cert-export --db-url 'postgresql://stork@localhost/stork' -f cakey

For evidence, without any postgresql URI defaults values are used (which I used too) and in that case I was correctly asked for the password
