[SL] Alternative setup of sql-ledger on multiple machines.

[dasDasein <da...@da...>]

Is it possible to run multiple installations of sql-ledger on different
machines, each connecting to a single (the same) postgresql dataset on a
server via ssh?  I would like to run sql-remotely on multiple machines
connected to a database using ssh without requiring an https connection.  If
so, how does once setup the same user account on the multiple sql-ledger
installations?
