You can't print the results of a query directly - the format they are
retrieved in is not just a regular PHP array. That's what the various
"fetch" options do - they pull the data out of the resultset into a
regular variable (single or array, depending on which one you use) so
that you can print it or otherwise treat it as a normal variable.

pg_fetch_result fetches a single value (string, integer, whatever it
might be) and stores it in a variable. You have to tell it exactly which
row and column from the result set you want. If you're only after one
value, use this.

pg_fetch_array and pg_fetch_assoc each fetch a whole row of data, as an
array. The different between them is that with the first one, the array
keys are just numbers, and with the second, it's an associative array
where the keys are the names of the columns in your database. If you've
only retrieved one row, but need more than one value from that row, use
one of these.

pg_fetch_all fetches *all* the rows from your result set, as a
multidimensional array. If your query is likely to have retrieved
multiple rows, use this.

Does that help?
