The URL template of JDBC used by dbeaver is jdbc:postgresql://{host}[:{port}]/[{database}]
>From the manual
"The host component is interpreted as described for the parameter host. In particular, a Unix-domain socket connection is chosen if the host part is either empty or starts with a slash, otherwise a TCP/IP connection is initiated."
In our case the host name does not start with a slash. So I conclude it is using TCP/IP.

We are using dbeaver, not psql. dbeaver also provides disable option for sslmode. I set sslmode=disable and it immediately rejected connection with error "SSL Mode off".
So the puzzle is -> in version 42.1.4 when we do not check "Use SSL " button, connection
fails with "SSL Mode off". In that version we check the box "Use SSL" and then in the dropdown
for sslmode, we select sslmode=require. Only then the connection passes.
In version 42.2.5 even if we do not check "Use SSL" it still behaves the same as
"Use SSL" checked and sslmode=require.
I was not able to import the security bulletin fully, but am I right in concluding
that JDBC 42.2.5 always turns on sslmode=require unless we explicitly set sslmode=disable.
Thanks for your help.
