Unable to connect to Cockroachdb

[rishavs]

I am having issues connecting to cockroachdb and I wonder if this is the same issue.

my connection string is something like;
postgres://[email protected]:26257/defaultdb?sslmode=verify-full&sslrootcert=cc-ca.crt&options=--cluster=somedbname

One of the reasons why I want to use Cdb is its support for ssl connections and was hoping that I could use it in my crystal api.

@rishavs I think the situation you are in is the same as #136. PR are welcome accordingly to #113.

@rishavs You need to add the cluster name to the db name as prefix, and also enable cleartext auth methods:
postgres://[email protected]:26257/somedbname.defaultdb?auth_methods=cleartext,md5,scram-sha-256&sslmode=verify-full&sslrootcert=cc-ca.crt
But sslmode=verify-full is not implemented.
