I tried postgresql endpoint, no dfference. But...

...well, I just managed to pass json request to add connection group. It worked:

% ./get-token.sh
HTTP/1.1 200
Content-Type: application/json
Transfer-Encoding: chunked
Date: Sun, 05 Apr 2020 21:53:20 GMT

{"authToken":"8EAD8FCE7185A54F0F98018F5640A06DC519CA66868BFA5BAF9035FDC913ACEB","username":"guacadmin","dataSource":"postgresql","availableDataSources":["postgresql","postgresql-shared"]}

% ./add-group.sh
HTTP/1.1 200
Content-Type: application/json
Transfer-Encoding: chunked
Date: Sun, 05 Apr 2020 21:53:33 GMT

{"name":"GRUPP1","identifier":"8","parentIdentifier":"ROOT","type":"ORGANIZATIONAL","activeConnections":0,"attributes":{"max-connections":"","max-connections-per-user":""}}

% cat add-group.sh
curl -i -X POST "http://127.0.0.1:6060/api/session/data/postgresql/connectionGroups?token=8EAD8FCE7185A54F0F98018F5640A06DC519CA66868BFA5BAF9035FDC913ACEB" -d '{"parentIdentifier": "ROOT", "type": "ORGANIZATIONAL", "name": "GRUPP1", "attributes": {"max-connections-per-user": "", "max-connections": ""}}' -H "Content-Type: application/json"

Created connection group GRUPP1. So, probably json should work with users too. 
I'll try to dig deeper :) I suspect that 500 errors happen because API
requires certain fields and not because of json/nonjson format.
