I have a database connection to a postgresql database on a non-default port, 5433.
TESTDB,5433 as the instance and I can connect with no errors.
If I open that connection properties again, the Instance is displayed with no port configured:
When I hit cancel and the double-click the connection, I connect successfully to the 5433 port (confirmed by checking the server status of the 5433 and seeing the incoming connection). Even after hitting
OK on the Instance without a port...the connection still connects to 5433. Only after expliciting specifying
TESTDB,5432 can I switch back to the 5432.
Since both instances have the same data schema (and often the same data), how would an ArcGIS user know which instance he or she is connected to?
