Thanks. I did search briefly for "PGadmin 4 system requirements" before asking, as well as "postgresql pgadmin version compatibility matrix" but didn't find anything of the kind.
I see now that the pgadmin site has on its homepage: "pgAdmin may be used on Linux, Unix, Mac OS X and Windows to manage PostgreSQL 9.2 and above." and "Click the PostgreSQL Documentation link to navigate to the Documentation page for the PostgreSQL open-source project; once at the project site, you can review the manuals for the currently supported versions of the PostgreSQL server." is in the documentation. Haven't found a referense to "currently supported version of the PostgreSQL server" (in regards to PGAdmin) in the Postgresql docs yet but shall keep looking. Thanks again for the quick reply. -- Sent from: http://www.postgresql-archive.org/PostgreSQL-pgadmin-support-f2191615.html
