Description:

In pg_hba.conf I have the following setup:
host all all laptop md5

Although the hostname gets resolved by the system (LAN DNS server) I still
get the no pg_hba.conf entry error.
If I enter the hostname and ip in the hosts file all works well.
I get the following error: (it seems the host name gets resolved but after
the deny)
