I am using postgresql 9.3 with pgadmin III, and Access 2013 as a
front end for data entry using (ODBC connection) linked tables, on a
Windows 8.1 (64).
I have one main database I am developing on a localhost:5432, with
four other test databases I had on the same localhost. A few weeks ago
the four test databases disappeared from the list in pgadmin III and
using the shell command to list the databases, only the main database
showed up.
A week ago, the four test databases reappeared and were apparently functional (in pgadmin I viewed the tables and they appeared fine). I turned off pgadmin and restarted, and the four test dataabases disappeared again.
Today, I turned on pgadmin and the four appeared again - I took a screenshot to confirm I am not hallucinating (!). Again, I turned off pgadmin, and restarted and they disappeared again.
