What you've probably run into here is that some packagers build Postgres
to put the server's socket file into /tmp, while others build it to put
the socket into /var/run/postgresql/ or some similar path.  Likely,
you are now using a new version of libpq.so that expects the latter
while your server is still doing the former.  You can override libpq's
default with "-h /tmp" or equivalent in order to connect.

            regards, tom lane

when you install PostgreSQL the installation copies all its binaries to their respective places and tries to start the server  afterwards.

This of course fails as the needed ports are already used by the running old PostgreSQL server.

So you end up with a mixture of new and old.

No idea whether it will be enough to stop the running PostgreSQL and the just restart the PostgreSQL service ..

Good morning,

 

I am preparing to upgrade my pqsl server from 9.3.5 to 9.6.12. I have installed the 9.6 rpm onto the server that has 9.3.5 running. Postgres is still running 9.3.5 on that server, but when I try to run psql I get the following message.

 

“psql: could not connect to server: No such file or directory

        Is the server running locally and accepting

        connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?”

The database is still running and working I just can’t use any of the client commands like psql, pg_dump….

And there is no "/var/run/postgresql/.s.PGSQL.5432" file.

 

Can someone help with this problem.
