I have a database where a pdf was encoded (possibly compressed) and stored in a blob field. What is the best method to decode that blob back into a pdf using perl? And what are some of the common methods of encoding a pdf for storage in a blob field?

You would need to know what algorithm (if any) was used to compress the PDF, and use the reverse for uncompression. There are many compression algorithms available and suitable, such as gzip, zip, bz2, etc.

is perl capable of decompressing any of those algorithms?

Sure, all available decompressors can be run from Perl. But first you need to know which one to use, or do some experimentation to find out which decompressor produces the goods.
