Hi Frank and lists members,

We use to identify different PostgreSQL clusters/databases with
PGServicefile: this gives flexibility to change PostgreSQL cluster and/or
databases without annoying users. Authentication of the users is done via a
personal authentication database.

Old, but still valid QGIS and PostgreSQL service connection file
documentation is here:
https://docs.qgis.org/2.14/en/docs/user_manual/working_with_vector/supported_data.html#service-connection-file

Rgs,

Pekka
