As Tom already said, the "host local allow" line has nothing to do with TCP/IP.

But if you want to explicitly specify a hostname, then use "-h <machinename>" or "-h <ip-adress>" as parameter to psql.

So what do the following commands return?
$ psql -h localhost testdb
(should be OK)

$ psql -h 127.0.0.1 testdb
(should be OK)

$ psql -h <ip-adress-of-machine> testdb
(should be rejected)

Maybe a stupid question, but does MacOS have the same path-format as Un*ces? (You wrote about connecting to your DB via
JDBCfrom a MacOS (on another machine?), or did I misinterpret that?) 

And you said that you never had to specify the host you connect to in your JDBC connect statement. Usually this is a
"host="parameter. I've never used JDBC, but ODBC, Pg, ADO (via ODBC), ... 

You posted an error message:

How exactly did you connect to your DB and from which computer?
