the first error brings up a SO post where someone suggests editing your
postgresql.conf file adding the line:
listen_addresses = '*'
Thanks; perhaps 'duckduckgo'ing is not as accurate ;) assuming the search engine query result referred to is somewhere in that 'stackoverflow' web site...
Changed the configuration file to include:
"
listen_addresses = 'localhost'
"
For now, no password for database until php is learnt a bit more. So far, after this configuration file change, connection to the postgresql database continues to fail, but the previous error (sign-in to database via command terminal) is solved.
The php web page continues to return:
"
Generic CPAC database Could not connect
"
Please, any other ideas to follow?

Please how to connect successfully to the postgresql database?
This looks to be more of a problem with your Postgres DB not allowing
the connection than anything specific to PHP. Couple of seconds Googling
the first error brings up a SO post where someone suggests editing your
postgresql.conf file adding the line:
listen_addresses = '*'
However, I would recommend only allowing the addresses you actually know
that should be connecting to this DB.
It also lists some advice about what changes you need to make to your
pg_hba.conf to allow access for all users with an encrypted password,
but you don't appear to actually be using a password on your database
(none of your connection strings have one, and the error is about
something else). I would always use a password for any DB, regardless of
how locked down it may be in other areas.
