mp3 Upload Failure - ownCloud 4.5.7 and PostgreSQL 9.2.3

[DPStokes]

I have just created a clean installation of ownCloud 4.5.7 (from tarball) with PostgreSQL 9.2.3 on Fedora 18 with Apache 2.4.3 and PHP 5.4.11 (PHP added as edit).

I am unable to upload mp3 files and the following error (cleansed to protect the innocent) is displayed in the Apache error log:
[Tue Mar 05 13:15:40.052830 2013] [:error] [pid 10562] [client xxx.xxxx.xxx.203:57945] PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22P02]: Invalid text representation: 7 ERROR: invalid input syntax for integer: "\x06"' in /xxxxxx/owncloud-4.5.7/lib/db.php:745

Image files upload fine as do wav files (although wav files don't display in the Music tab).

Ignore.... set PHP value post_max_size (perviously only 256K) to match upload_max_filesize
