I managed to mess up postgresql-10.3 on this Slackware-14.2 desktop server/workstation. It worked OK until I tried adding access to an another application.
The problems have been resolved by upgrading 10.3 to 10.5 using the SlackBuild.org script. There was a minor error when that was changed from version 9 to 10 and after correcting that the build went well. Long story short: the server started and I can once again access databases using psql. Now I go back to getting GRASS to connect to the database after modifying postgresql.conf to accept connections from all hosts on my office network. My thanks to Adrian and Andrew for their patient help. Best regards, Rich
