Yes, aware but one step at a time, slowly(!)
As a non-programmer, want to test ability to comprehend the concepts
first, before security implementations.

First, sorry for the mistake to type a sanitised version of code.
Should have been:
"$query=$_GET['databasecolumn'];"
After some rtfm, confused as a non-computer-programmer why it is
necessary to set the $_GET parameter.
The overall simple scenario is to view a postgresql database in a
series of
Readers,
Suppose:
$query=$_GET['databasecolumn'[;
$anotherquery=pg_query($databaseconnection, 'SELECT * FROM
databasename WHERE databasecolumnname="'.$query.';"');
Two errors are reported:
PHP Notice: Undefined index: databasecolumnname
PHP Warning: pg_query(): Query failed: ERROR: column
