Using Fedora33 rn, tried to install Postgresql, was succesful initializing first db, haven't got any errors. Also installed pgadmin4 but couldn't create a server.
su -i -u postgres -c "psql"
tried this command and got: `
psql: /usr/pgsql-11/lib/libpq.so.5: no version information available (required by psql)
psql: /usr/pgsql-11/lib/libpq.so.5: no version information available (required by psql)
psql: symbol lookup error: psql: undefined symbol: PQgssEncInUse, version RHPG_10
tried reinstalling as mentioned and pg_ctl: error while loading shared libraries: libpq.so.5 but didn't work either.
