I upgraded to postgres 9.6.0. I am not able to start a new database instance. On
pg_ctl -D /localscratch/sandeep/pgsql_sa_5579 init
I get error
initdb: could not look up effective user ID 21073: user does not exist
I am not sure if this is OS setup issue or a database issue. I am on CentOS release 6.8.
