Description:

Hi,
 I have installed 
CREATE EXTENSION CUBE;
CREATE EXTENSION earthdistance;

Post which I ran the following query:
SELECT (POINT (19.974, 72.756)<@> POINT (19.195, 72.959)) AS DISTANCE;

The answer came back as 21.17534 miles whereas the actual distance (as crow
flies) is 55.42 miles which I have checked from 2-3 websites. (Google maps
gives a greater distance which is travel by road & this value has been
ignored).

I know both the places and the distance between both of them cannot be 22
miles. It has to be in excess of 50 miles atleast. What am I missing?

By your queasy it looks like you are comparing two points in the Norwegian Sea.

I think you may have swapped your latitude and longitude, and are
actually looking for:

postgres=# SELECT (POINT (72.756, 19.974)<@> POINT (72.959, 19.195))
AS DISTANCE;
  distance

 55.421996899143366

ssl connection with certificate

Description:

Good morning. Following the instructions
https://www.postgresql.org/docs/11/ssl-tcp.html I can't establish a local
connection with certificate. In the pg_hba.conf 
hostsslall all 127.0.0.1/32md5
clientcert=1

And in the postgresql.conf:

ssl_cert_file = '/etc/postgresql/11/main/server.crt'
ssl_key_file = '/etc/postgresql/11/main/server.key'

server is a certficate is generated.
The error all the time is the same, it cannot connect because either the
server is not activated or something is missing.

I need a possible solution. The installation I have done is the basic sudo
apt install postgresql on debian 10

Thanks and best regards,
