Perl has base64 encode / decode - that might be more suitable for storing as UTF-8

Hello, <br />
<br />
can someone provide me with hints on how to store binary files with postgreSQL. I have followed this short perl tutorial. <a href="http://www.linuxconfig.org/Simple_Perl_example_how_to_store_and_retrieve_binary_file_in_and_from_the_postgresql_database" rel="ugc">http://www.linuxconfig.org/Simple_Perl_example_how_to_store_and_retrieve_binary_file_in_and_from_the_postgresql_database</a><br />
<br />
It works and I'm able to store and retrieve data using the scripts on that page. However I have error messages coming up on my stderr:<br />
DBD::Pg::st execute failed: ERROR: &nbsp;invalid byte sequence for encoding<br />
&quot;UTF8&quot;: 0x8b<br />
<br />
where I'm trying to store gziped file. This I assume is because I need to escape binary strings before storing them on UTF8 ( Unicode ) database. &nbsp;This can mean that escape_bytea subroutine is not working properly.<br />
<br />
can anyone help in this matter?<br />
<br />
thank you<br />
<br />

Store binary files with PostgreSQL

PostgreSQL is an object-relational database management system with an emphasis on extensibility and standards-compliance. As a database server, its primary function is to store data securely, supporting best practices, and to allow for retrieval at the request of other software applications. PostgreSQL implements the majority of the SQL2011 standard, is ACID-compliant and transactional using multiversion concurrency control (MVCC), and handles complex SQL queries using many indexing methods that are not available in other databases. It is cross-platform and runs on many operating systems including Linux, FreeBSD, OS X, Solaris, and Microsoft Windows.

PostgreSQL

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.
