Question

I am new to postgresql. I am trying to use postgresql with ruby on rails. I have just installed postgresql and I have just created my database. But when I try to run postgresql on localhost on port 5432 I get the above error.

Answer 1

Yeah, I figured out the solution:

I changed my settings in pg_hba.conf to

# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust

where initially instead of trust it was md5 . Then just doing service postgresql restrart did the trick!!
