I know this is a common problem because the web is full of advice. Sadly none of it has worked for me.
I re-installed PostgreSQL 10 on Ubuntu 18.04 after removing it with --purge and now I can't get back into it.
I have assigned a Linux password to the postgres user and I can sudo or su but psql is demanding its own password for its postgres user. The log says ...
2020-06-12 14:03:00.019 AEST [22214] postgres@postgres FATAL: password authentication failed for user "postgres"
2020-06-12 14:03:00.019 AEST [22214] postgres@postgres DETAIL: User "postgres" has no password assigned.Connection matched pg_hba.conf line 92: "host all all 127.0.0.1/32 md5"
No password assigned. Which I knew. So I removed that "host all" line from pg_hba leaving only the "local all" lines and failed again ... the log now says ...
2020-06-12 14:09:12.846 AEST [22462] LOG: database system is ready to accept connections

I am fairly lost here. My objective is to get the postgres user re-established, get my own user re-established, re-load the dump files and get back into production.
Any advice appreciated
Thanks
Mike
