Hello,

I am very new to PostgreSQL. I am trying to connect to database via a different user which is created by me.

psql -U user1
but this gives me error message saying database user1 does not exist.

When I try psql -d mydb -U user1 this works fine.

Can any body suggest me if there is any way to connect to database through psql command line without using the -d database parameter.

Hello,

When connecting to the PostgreSQL server through psql, the database must be specified so that PostgreSQL knows which database to run the SQL against.

For example, if you had an additional DB on your PostgreSQL server other than mydb called mydb2, and you connected to mydb2 through psql, queries against tables existing in mydb would fail because they do not exist in mydb2.

Therefore, the database must always be specified.

Just set up the the environment variables as explained in the manual:
