Hi,

We did the upgrade of PostgreSQL 10 to 12 on linux server. Everything was fine (can connect via pgAdmin, data is there…) except two tablespaces which are still in directory for PostgreSQL 10.

So we followed these steps to move tablespaces: https://www.enterprisedb.com/blog/moving-tablespaces-postgresql

The problem was at the end while executing:

$ pg_ctl start

This is the error trace:

pg_ctl: another server might be running; trying to start server anyway

waiting for server to start....postgres: could not access the server configuration file "/var/lib/postgresql/12/main/postgresql.conf": No such file or directory

stopped waiting

pg_ctl: could not start server

Examine the log output.

The configuration file path is /etc/postgresql/12/main/ postgresql.conf and it is configured in /var/lib/postgresql/12/main/postmaster.opts:

“/usr/lib/postgresql/12/bin/postgres "-D" "/var/lib/postgresql/12/main" "-c" "config_file=/etc/postgresql/12/main/postgresql.conf"

Why does pg_ctl complains about thepostgresql.conf path?

I'm guessing you are on Debian/Ubuntu?

If so what does the below show?:

pg_lsclusters

If it shows clusters then do:

sudo pg_ctlcluster 12 main start


If the above is not correct, then what user where you doing:

pg_ctl start

as?



Thank you,

Tanja
