Ah bugger. It is because I have to use pg_field_num() instead of
assuming the fields are numbered from 0 and up continuously.

Description:
------------
For some queries, pg_field_type() returns the wrong field type. It
seems to happen when you do a "SELECT *" and there are more than one
table in the FROM-clause, with common columns eliminated.
I tested with postgresql 7.4 and postgresql 8.1, with the same result.
Reproduce code:
---------------
<?php
$params = "host=localhost dbname=testdb user=testuser
password=123456";
pg_pconnect($params);
pg_query("begin");
pg_query("CREATE TABLE test1(a integer)");
pg_query("CREATE TABLE test2(a integer, c varchar)");
pg_query("INSERT INTO test1 VALUES (1)");
pg_query("INSERT INTO test2 VALUES (1,'aa')");
$res = pg_query("SELECT * FROM test1 INNER JOIN test2 ON
test1.a=test2.a");
$row = pg_fetch_assoc($res);
$col_i=0;
foreach ($row as $field_name => $dummy) {
var_dump($field_name);
$type = pg_field_type($res, $col_i++);
var_dump($type);
if ($field_name == "c") {
assert($type != "int4");
}
}
pg_query("rollback");
?>
Expected result:
----------------
The type of column "c" should be "varchar"
Actual result:
--------------
The type of column "c" is "int4"
