It works fine for me, see:
teste=# SELECT table_schema, table_name FROM information_schema.tables
WHERE table_schema = 'public';
table_schema | table_name
--+
public | id
var_dump(pg_meta_data($x, 'id'));
array(1) {
["id"]=>
array(6) {
["num"]=>
int(1)
["type"]=>
string(4) "int4"
["len"]=>
int(4)
["not null"]=>
bool(false)
["has default"]=>
bool(false)
["array dims"]=>
int(0)
}
}

Compile PHP using --enable-debug option and provide a new, useful
backtrace.

postgres-8.3.5 is the version I'm using here (server & libs)
