I'm too new at this to understand. That's why I ask. What I don't
understand is this: is sql generic as opposed to specific comands in mySQL
and/or postgreSQL?
I now understand that in my problem below you are right, there was an
sqlconnect function created as you suggested below.
Then, what would be the reason to use this sqlconnect function rather than
pg_connect? Can't parameters be passed on to the pg_connect in the same way
as they are passed on to the created sqlconnect? It seems like extra work
or a bit of redundancy in creating a function that exists?

This is what I found (the MySQL references are there because the db was
migrated from MySQL to PostgreSQL):

function SQLConnect($params='') {
global $dbh;
/*
* MySQL equivalent:
* $dbh=mysql_pconnect( $db_server,$db_user,$db_password );
*/
if(isset($params['server'])) {
$connect="host=".$params['server'];
}
else {
$connect='host=localhost';
}
if(isset($params['port'])) {
$connect.=' port='.$params['port'];
}
else {
$connect.=' port=5432';
}
if(isset($params['user'])) {
$connect.=' user='.$params['user'];
}
if(isset($params['database'])) {
$connect.=' dbname='.$params['database'];
}
if(isset($params['password'])) {
$connect.=' password='.$params['password'];
}
$dbh=pg_pconnect($connect);
}
