Postgresql: Scripting psql execution with password

Question

How can I call psql so that it doesn\'t prompt for a password?

This is what I have:

psql -Umyuser < myscript.sql         


        

Answer 1

You have to create a password file: see http://www.postgresql.org/docs/9.0/interactive/libpq-pgpass.html for more info.

Answer 2

An alternative to using PGPASSWORD environment variable is to use conninfo string according to the documentation

An alternative way to specify connection parameters is in a conninfo string or a URI, which is used instead of a database name. This mechanism give you very wide control over the connection.

$ psql "host=<server> port=5432 dbname=<db> user=<user> password=<password>"

Answer 3

Use -w in the command: psql -h localhost -p 5432 -U user -w

Answer 4

If you intend on having multiple hosts/database connections, the ~/.pgpass file is the way to go.

Steps:

1. Create the file using vim ~/.pgpass or similar. Input your information in the following format: hostname:port:database:username:password Do not add string quotes around your field values. You can also use * as a wildcard for your port/database fields.
2. You must chmod 0600 ~/.pgpass in order for it to not be silently ignored by psql.
3. Create an alias in your bash profile that runs your psql command for you. For example:alias postygresy='psql --host hostname database_name -U username' The values should match those that you inputted to the ~/.pgpass file.
4. Source your bash profile with . ~/.bashrc or similar.
5. Type your alias from the command line.

Note that if you have an export PGPASSWORD='' variable set, it will take precedence over the file.

Answer 5

PGPASSWORD=[your password] psql -Umyuser < myscript.sql
