Yeah, I get the sense I need to simplify the situation, if only to eliminate some distractions from the story. This morning I was thinking I want to play around with pg_hba.conf settings some more, but after that I'll do some pg_dumps and uninstalls and see how things behave. Oh, trying: /usr/bin/psql --dbname=doom --username=doom -p 543x As login 'doom' the connection happens only for port 5432, as login 'postgres' the connection fails differently for port 5432: psql: FATAL: Peer authentication failed for user "doom" (Like I said, I need to play with pg_hba.conf a bit.) But that actually surprises me, I would've expected it'd be on port 5434, because that's the most recent binary install, not the original 9.4 version: /usr/bin/psql -V psql (PostgreSQL) 9.6.1 /etc/postgresql/9.6/main/postgresql.conf port = 5434 # (change requires restart) /etc/postgresql/9.4/main/postgresql.conf port = 5432 # (change requires restart) On Sun, Dec 4, 2016 at 7:06 AM, Adrian Klaver <adrian.klaver@xxxxxxxxxxx> wrote: > On 12/03/2016 09:38 PM, Joseph Brenner wrote: >>> >>> So is the 9.4 instance the production/live database? >> >> >> Essentially, but it's not heavily used: this is me messing around on a dev >> box. >> >>> So what happens when you specify the port in your psql connection, eg: >>> /usr/local/pgsql/bin/psql --dbname=doom --username=doom -p 5432 >>> /usr/local/pgsql/bin/psql --dbname=doom --username=doom -p 5433 >>> /usr/local/pgsql/bin/psql --dbname=doom --username=doom -p 5434 >> >> >> With /usr/local/pgsql/bin/psql, only "-p 5433" connects, the >> other two complain like so: >> >> psql: could not connect to server: No such file or directory >> Is the server running locally and accepting >> connections on Unix domain socket "/tmp/.s.PGSQL.5434"? >> > > Alright how about?: > > /usr/bin/psql --dbname=doom --username=doom -p 5434 > > My suspicion is that when you did the source build you got some cross > contamination of libraries. > > If it where me I would get rid of the instance that you built from source, > assuming that there is nothing important on it. > > > > -- > Adrian Klaver > adrian.klaver@xxxxxxxxxxx -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
