What you configure is .authinfo then how I understand, the sql-mode
would search for user/password and server datails in .authinfo by
using that function. Unless you are programming you need not use that
function. And function is prefixed sql- only because it belongs to sql
mode, not that it is doing any SQL itself.

I have not configured authinfo as I mostly work with local database.

Instead I have configured environment variables:

export PGDATABASE="databasename"
export PGUSER='username'
export PGCLIENTENCODING='UTF8'

You better say what you wish to achieve, do you wish to remember
credentials for remote databases?

File ~/.authinfo is in format:

host localhost port port-number user user-ID password password
