oid vs bytea in Postgresql

Okay, here is the deal, I am working on a project which requires me to store files in my database. But I have recently just switched to postgresql from mysql, so I had to do some research on what methods postgresql offers for file storage. In mysql GLOB would have been my choice, but postgresql offers two methods, BYTEA which is postgresql’s answer to GLOB, or store the files in Large Objects (oid).

I asked around to find out what method would be the fastes, but I could not find the answer I was looking for, so I ended up spending the night testing it for myself, this blog will show the results.

if ($mail=='') return '';
$mail = str_replace(array('@',':','.'), array('@',':','.'), $mail);
$len = strlen($mail);
$i=0;
while($i< $len) {
$c = mt_rand(1,4);
$par&#91;&#93; = (substr($mail, $i, $c));
$i += $c;
}
$join = implode('"+ "', $par);
return '<script language="javascript">
<!--
document.write("'.$join.'")
//-->
';
}
